Have an older CPU?
We no longer sell older processors, but they belong in the table: they show whether a GPU swap is enough or the whole platform needs replacing. Send us your configuration for a free upgrade quote; old hardware counts as a trade-in.

Frequently asked questions
Which CPU is best for the RTX 5090?
From our range we recommend the Ryzen 7 7800X3D (6 % loss at 1440p, 283 FPS on average). A sensible minimum is Ryzen 5 9600X (13 % loss at 1440p, 254 FPS on average). For the last few percent: Ryzen 7 9850X3D (0 % loss at 1440p, 316 FPS on average). All of them are in our configurator and we build the PC for you.
Is a Ryzen 5 5600 enough for the RTX 5090?
At 1440p the Ryzen 5 5600 averages 207 FPS with the RTX 5090, 27 % less than the strongest CPU (serious bottleneck). At 4K the gap is 10 %. In esports at medium settings (CS2, Valorant, Dota 2) the CPU matters more: 412 FPS on average versus 673 FPS with the Ryzen 7 9850X3D.
What resolution is the RTX 5090 good for?
With maximum settings and no upscaling the GeForce RTX 5090 is a 4K card: with the Ryzen 7 9850X3D it averages 110 FPS in demanding games (Cyberpunk 2077, Kingdom Come 2, Battlefield 6…) and 583 FPS in esports. With DLSS/FSR you can go one resolution higher.
How many FPS does the RTX 5090 get with the Ryzen 7 7800X3D?
Without upscaling (demanding games at Ultra, esports at medium): CS2 1080p: 740 FPS, Fortnite 1440p: 150 FPS, Cyberpunk 2077 4K: 105 FPS, Battlefield 6 4K: 93 FPS, Kingdom Come 2 4K: 120 FPS. These are the same numbers the “How many FPS?” calculator shows on every PC.
Does an older CPU like the Ryzen 5 3600 bottleneck the RTX 5090?
Yes, noticeably: at 1440p the Ryzen 5 3600 gives 41 % lower FPS than the strongest CPU (159 FPS on average; in esports at medium settings 6 %). With this card a platform upgrade pays off – send us your configuration and we will quote the upgrade; the old parts count as a trade-in.
