A GTX 980 is still a perfectly usable 1080p card in 2026 — it is roughly GTX 1070 class, and it will hold 60 fps in most esports and older AAA titles. What kills it is the CPU sitting next to it. Almost every 980 still in service is bolted to a Haswell or Sandy Bridge chip from the same era, and in modern games that CPU runs out of single-thread speed long before the GPU runs out of shaders. You see it as stutter and 1% lows in the 20s while the GPU sits at 60% usage.
There are two honest paths. Stay on your board and buy the best chip your socket takes — cheap, five minutes of work, and it buys real frames if you are currently on a dual-core or a locked i5. Or replace the platform — CPU, board and RAM together — which costs more but is the only route to a chip that will still be fine after the 980 is gone. Both are covered below, with the socket named for every pick so you do not buy a processor your motherboard cannot take.
One thing to settle first: check what you actually have. Open Task Manager, look at the Performance tab while you play, and if the CPU is pinned near 100% while the GPU idles below 70%, the CPU is your problem and this page is for you. If the GPU is at 99%, the 980 is the limit and a new processor will change nothing.

The picks, in detail
AMD Ryzen 5 5600
The best value new chip you can put behind a GTX 980. Six cores, twelve threads, 65 W, and it drops into any AM4 board with a BIOS update — so if you already own an AM4 system it is a pure swap. If you are starting fresh, AM4 boards and DDR4 are cheap now, which keeps the whole platform cost near what a single mid-range CPU used to be.
- 6 cores / 12 threads
- 3.7 GHz base, 4.6 GHz boost
- 65 W TDP, runs cool on the stock cooler
- Socket AM4, DDR4
- Best frames-per-dollar of anything here
- Drop-in for existing AM4 owners
- Massively overpowered for a 980, so it survives the next GPU
- AM4 is a dead-end socket — no future CPU upgrades
- Needs a BIOS update on older 300 and 400-series boards
Intel Core i5-12400F
The Intel answer at the same price bracket, and the one to pick if you want a socket with a little life left in it. Six modern P-cores, no efficiency cores to complicate scheduling, and single-thread performance well ahead of anything from the 980’s own era. LGA1700 boards also take 13th and 14th generation chips, so there is a genuine upgrade path.
- 6 P-cores / 12 threads
- Up to 4.4 GHz boost
- No integrated graphics (F suffix)
- Socket LGA1700, DDR4 or DDR5 depending on board
- Excellent gaming performance per dollar
- LGA1700 boards accept later Intel chips
- DDR4 boards let you reuse existing RAM
- Needs a new motherboard — this is a platform swap, not a drop-in
- No integrated graphics, so you cannot troubleshoot without a card
Intel Core i3-12100F
Four fast modern cores for the price of a game. This is the cheapest new CPU that will completely stop being the bottleneck for a GTX 980 — its per-core speed is roughly double a 2014 i5, and four cores is still enough for the kind of games a 980 runs well. The pick if the budget is genuinely tight and the 980 is staying for another year or two.
- 4 P-cores / 8 threads
- Up to 4.3 GHz boost
- 58 W base power
- Socket LGA1700
- Cheapest way onto a modern platform
- Single-thread speed embarrasses any Haswell i7
- Very low power and heat
- Four cores shows its limits in heavily threaded new releases
- Still requires a new board and RAM
AMD Ryzen 5 5500
The cheaper sibling of the 5600. Same six cores and twelve threads, lower clocks and — the detail people miss — only PCIe 3.0. That last part does not matter here at all, because a GTX 980 is a PCIe 3.0 card. If you are pairing it with this GPU specifically, the 5500 gives you almost all of the 5600 for noticeably less money.
- 6 cores / 12 threads
- Up to 4.2 GHz boost
- PCIe 3.0 only
- Socket AM4, DDR4
- Very cheap for six modern cores
- The PCIe 3.0 limitation is irrelevant with a 980
- Drops into existing AM4 boards
- Meaningfully slower than the 5600 in CPU-bound games
- PCIe 3.0 will hurt if you later fit a modern GPU
Intel Core i7-4790K
The best chip an LGA1150 board will ever take, and the single most cost-effective upgrade if you are running a 980 on a Z87 or Z97 motherboard. Four cores, eight threads, 4.0 GHz base — this was the fastest gaming CPU of the 980’s launch year, and on the used market it now costs less than a good mouse. No new board, no new RAM, no reinstall.
- 4 cores / 8 threads
- 4.0 GHz base, 4.4 GHz turbo
- Unlocked multiplier
- Socket LGA1150, DDR3
- True drop-in for Haswell boards
- Very cheap used
- Unlocked, so there is headroom on a Z-series board
- Used only — new stock is gone
- Runs hot and needs a decent cooler
- A dead end: LGA1150 has nothing beyond this
Intel Core i5-4590
The absolute floor. If your 980 is currently behind a Pentium, an i3, or a low-end Haswell i5, this is the cheapest part on this page that removes an obvious bottleneck. Four real cores at 3.3 GHz, no hyperthreading, and it costs about as much as lunch on the used market. Nobody should buy this as a target — buy it as a stopgap while you save for a platform swap.
- 4 cores / 4 threads
- 3.3 GHz base, 3.7 GHz turbo
- 84 W TDP
- Socket LGA1150, DDR3
- Almost free used
- No platform change needed
- Enough for older and esports titles at 1080p
- Four threads is genuinely limiting in modern games
- Will still bottleneck the 980 in CPU-heavy scenes
Intel Core i7-6700K
The Skylake equivalent for anyone on an LGA1151 board — Z170 or Z270. A similar four-core, eight-thread layout to the 4790K but on DDR4 with slightly better per-clock performance, and it overclocks well. Worth it only if your board already takes it; buying an LGA1151 board in 2026 to run this chip makes no sense next to a 12400F.
- 4 cores / 8 threads
- 4.0 GHz base, 4.2 GHz turbo
- Unlocked multiplier
- Socket LGA1151 (100 and 200 series), DDR4
- Drop-in for Skylake and Kaby Lake boards
- DDR4 platform
- Overclocks comfortably to 4.4-4.6 GHz
- Used market only
- Does not fit 300-series LGA1151 boards despite the same socket name
Intel Core i5-10400F
Six cores, twelve threads, and a used price that has fallen through the floor now that LGA1200 is two generations behind. Comfortably faster than any Haswell chip in modern games and a genuine sweet spot if you find a cheap B460 or B560 board bundled with it. This is the budget platform swap.
- 6 cores / 12 threads
- Up to 4.3 GHz boost
- No integrated graphics
- Socket LGA1200, DDR4
- Six recent cores for very little money
- Cheap boards and DDR4
- Runs cool and quiet
- Locked multiplier, and B-series boards cap memory speed
- LGA1200 is another dead-end socket
AMD Ryzen 5 3600
The chip that made six cores normal, and still a completely sensible partner for a 980. It is a straight drop-in for almost every AM4 board without a BIOS update, which is exactly what you want if you are upgrading from a first-generation Ryzen and cannot easily flash the firmware.
- 6 cores / 12 threads
- 3.6 GHz base, 4.2 GHz boost
- 65 W TDP, ships with a cooler
- Socket AM4, DDR4
- Widest AM4 board compatibility of any six-core
- Includes the Wraith Stealth cooler
- Plenty of headroom over a GTX 980
- Slower than the 5600 for similar money now
- Benefits a lot from fast RAM, which adds cost
AMD Ryzen 7 5700X
The pick if the machine does more than game. Eight cores and sixteen threads at 65 W, on the same AM4 socket as the 5600 — so it is the same drop-in, just with double the cores for video editing, compiling or streaming while you play. For gaming alone next to a 980 it is overkill, and that is the point: it will still be a good CPU three graphics cards from now.
- 8 cores / 16 threads
- 3.4 GHz base, 4.6 GHz boost
- 65 W TDP
- Socket AM4, DDR4
- Enormous multi-core headroom for the money
- Same easy AM4 drop-in as the 5600
- Handles streaming and editing without breaking a sweat
- No gaming benefit over the 5600 with this GPU
- No bundled cooler
Buying tips
- Confirm the bottleneck before you spend anything. Run the game you care about with Task Manager or an overlay open. CPU near 100% with the GPU under 70% means the processor is the limit. GPU at 99% means the 980 is, and no CPU on this page will help.
- Match the socket, not the brand. LGA1150 takes the 4790K, LGA1151 (100 and 200 series) takes the 6700K, LGA1200 takes the 10400F, LGA1700 takes the 12th-generation chips, and AM4 takes every Ryzen listed here. A 12th-gen Intel chip will not fit a Skylake board despite the socket names looking similar.
- A drop-in upgrade is worth far more than its benchmark score suggests. Reusing your board, RAM, cooler and Windows install turns a $60 CPU into a $60 total. A 12400F that scores 40% higher can easily cost $300 once the board and DDR4 are in the basket.
- Do not pair a 980 with anything above a Ryzen 5 or Core i5 for gaming alone. The GPU is the ceiling. Spend the difference on the graphics card instead — a used RX 6600 or RTX 3060 is a bigger jump than any CPU here.
- Check your power supply if you are also swapping the platform. A GTX 980 draws around 165 W and wants two 6-pin connectors. Ten-year-old supplies that were fine in 2015 are often well past their useful life, and a failing one looks exactly like an unstable CPU.
- Buy used processors from sellers with returns. Chips rarely fail, but bent socket pins on AMD parts and vendor-locked Dell or HP boards are real risks. A return window costs nothing and covers both.
