780 to ski on 2500k

An i7 would help cpu scaling as you wont have as much cpu bottleneck allowing for higher frame rate but will it be low on a 2500k ?

I have 2 780 ti and an i5 2500k. Would there be much difference anywhere if I were to change to an i7?

Yes you're starving your premium gpu's. You want an i7 minimum ideally if you have two top gpu's from either side.
 
Try find yourself a cheap second hand i7 2600K or i7 2700K and overclock it to 4.5 and you will be good to go and should be a nice cheap upgrade once you sell your i5 2500K.

If you look on ebay there is some i7 2600K for £100 to £115 and last one that sold on the members market went for £115. Your i5 2500K should sell for £85-£95.


i7 2700K are only i7 2600K with a 0.1Ghz speed bump, the silicon is exactly the same but they seem to go for more at the moment, so get the i7 2600K and it will overclock the same as an i7 2700K if they are both good chips, silicon lottery remember.

MOOGLEYS it's because of you resolution, you are taxing the GPUs more than the CPU at that resolution. You bring up a good question, opstrat what resolution do you use ?

Fair enough I no longer have the 780's so cannot add anything else or try at a lower res now. This chap does a decent write up for comparing 1440p 2500k and 4770k using AMD cards and it includes some of them god awful benchmark's as well.. :)

2500k vs 4700k 2560x1440
 
I switched out a 2500K for a 3930K for SLI 680's and the difference was huge. No longer was the CPU being the bottleneck and at 4.625Ghz, the 3930K handles a pair of Titans with ease at 1080P/1440P.

Game dependent of course but games like BF3/4 require a good chunk of clocks on the CPU. Try it OP and see how you get on. If you feel they are being held back, go for an upgrade on the CPU :)

Ohhh and I didn't know a 2500K could ski :D
 
I seen some pretty nice increases going from my 2500k to a 4770k :) I say go for it. It particularly helps with multi-GPU setups.
