i5 2500k Bottleneck for GTX 1080

[zeus1356]

Hello all,

Sorry for another bottleneck thread, but I just would like to be sure before making a major investment.

I want to buy the new GTX 1080 when it comes out, and I have an i5 2500K overclocked to 4.3 GHz. Will that bottleneck the 1080? I know some games may favor the CPU a bit more but I'm really mainly interested to see if this will have a material bottleneck on the 1080.

Also, I am still running a mobo with PCI-express 2.0. Will that cause a bottleneck if i plug the 1080 into that?

Thanks for the replies, you guys are great!

no CPU wise you should not have a significant bottleneck. And as far as PCIe 2.0 is concerned you again should be fine. If your running an 16x link then in terms of PCIe 3.0 throughput its an 8x link...if 8x then in PCIe 3.0 terms its 4x...etc. Point is this has been tested again and again GPU/PCIe gen after GPU/PCIe gen. the lower speed links make very little difference in GPU performance.

Actually at that OC level, no. Not really. I think your CPU will be just fine to stretch 1080 legs assuming you have adequate monitor setup to abuse it.

Also, it would be long list before PCIe gen2 bandwith became a bottleneck factor.

Cool, thanks for your help guys.

It's crazy that a processor that was released 5 years ago can still hold up with the today's fastest GPU!

yeah it is cool and a little sad. I run a Sandybridge CPU myself, though its a i7 3930k @ 4.2ghz (4.6ghz capable but never need that much for gaming) with 2 GTX 980's and plan on some GTX 1080's (might wait for Ti since gaming at 4K and want VR soon). It's nice in you can keep an older system longer since intel hasn't raised the performance bar that high to make an upgrade essential. But the same reasoning makes it sad, I miss the larger performance increases of yesteryear. I actually still run a i7 970 rig @4ghz for my wifes gaming system and even it is capable in pretty much every game running 2 GTX 780's in SLI on high to ultra setting with 16x by 8x filtering as long as your only shooting for 60fps....if shooting for 90-144fps not so much.

Glad I did some searching before opening a new post with the same question! Zeus, have you bought the 1080 yet, and if so, how are your fps rates? I also have an i5-2500 but @ 3.30GHz.

I'm also curious as to what monitor you are using? Mine is crapping out and I just bought a29' LG one but I think I would be wasting potential with the GTX 1080. Anyone else have thoughts on the monitor as a potential bottleneck?

I ended up going with two gtx 1080s in SLI with a sandybridge based CPU and couldn't be happier. though i run i7 3930k on a 4K gaming rig. You should have zero issues with bottlenecks unless your gaming at over 100+ FPS at which point a new CPU will only net you another 10-15% assuming your GPU can hit that frame rate at the resolution your gaming at. So in practice 1080/1440p is probably good until 100fps or so with your CPU and at 4K there is no GPU that can go that fast by itself so its not even worth the worry.
