Will my Core2Duo E8400 bottleneck 760 GTX SLI? How much? - Page 2

post #11 of 16
You're already bottlenecking that single 760 really badly as is. I have a Core 2 Duo rig, and tons of 7xxx series graphics cards. Throwing my 7970 in here, I see no difference from the 7770 that I have installed currently (3GHz C2D and 4GB DDR2). So considering I see zero increase from a 7770 to a 7970, yeah I wouldn't bother with a second 760 till you upgrade your CPU, motherboard, and RAM.

Doh

I'm running a 7870 in a Windsor box and it bottlenecks like crazy bad, cpu usage always pegged with 30-40% gpu usage.

Sorry for bumping this 2 month old thread but I'm in the same situation.
I have the pc in my sig, dual core e5200 and a 760 but I see my GPU reach 90% + usage. From what I know, it should not reach that high if there is a bottleneck. I know there is a bottleneck but why is this dual core capable of making the card reach 90%+ while gaming?


I'm not asking what to buy etc. I will get a haswell and upgrade entire pc for sure, just want to understand things better here tongue.gif

In short, yes.

I had an e6600 oc'd to 3.1, while it performs worse that you cpu, get this, my e6600 was bottlenecking a 5850 from 2010. I don't even wanna know what would have happened if I had installed my current 7950 in that rig. I literally went from running medium/low settings at 35fps in BF3 to maxing it out with high/ultra settings while getting 30-40fps with the 5850.
