I plan on upgrading my computer in the near future and was going with dual 760's (760 Twin Frozr OC 2gb) in SLI. Now looking back I don't know if this is good idea. I was hoping someone may have some knowledge about these graphic cards bottlenecking with the i5-2400.

Here is what I plan to upgrade to:

-Cooler Master Hyper 212 EVO
-ASRock Z77 Extreme4
-Kingston HyperX Grey 8GB 1600mhz
-MSI GeForce GTX 760 2GB (2-Way SLI)
-Corsair Builder 750w Power Supply

Current Build:

-i5-2400 3.1ghz
-4gb 1333mhz ram
-XFX 6870
-500w PSU
-500gb hard drive

They other stuff not listed are acer's own branded products as I bought a pre-built computer then upgraded it a bit.

Thanks.

I suggest just grabbing the i5 3570K and a single 760, then getting another 760 down the line. This will eliminate any chances of a bottleneck, and it will give you the ability to OC for further future proofing. Also, adding another graphics card is a lot easier than replacing a CPU, so you might as well get it out of the way.

If I go down this route do you think ill see a significant performance in games? Also do you think ill be able to overclock the CPU with the Cooler Master Hyper 212 EVO well?

Thanks for the fast reply by the way!

My GTX 780 runs at 99% while my i5-2500 runs at 60% during Skyrim (which is CPU hungry). I doubt you would have ANY bottleneck with SLI 760's. I suggest do it.

Edit: If I were to SLI my GTX 780, I would have only a slight bottleneck...so you should be golden.
If you do stick with your NON bottlenecking CPU, I also say just grab another 4 GB of whatever ram you have now, as Sandy Bridge (unless overclocked) only sees ram as 1333mhz as I have tried a friends ram in my computer and turning on the profile in BIOS (his ram was 1600mhz) just to see if it would run faster, it didn't.

Double Edit: Now I want chicken...

Very few modern games are CPU-bound once you hit sandy-bridge era cpus. Yes a 3570k will increase cpu performance by ~15%, but in games getting two 760s will show framerate increases far beyond 15% closer to a 2-3X increase in framerate. Getting two 760s now and waiting for a platform upgrade seems like your best plan.

Ok, thanks for the fast replys guys going to go with getting the two 760s and upgrading my cpu in the future, as Heironious said there should be no bottleneck and im thinking the same way taking in what kevin said about modern games and how there not as cpu bound notp as cpu bound.

Thanks again.

The Cooler Master hyper 212 will yield decent overclocks with the i5. You could expect overclocks somewhere in the 4.3-4.4GHz area.

I would get a 2x4gb pack of RAM if your motherboard will support it. Then I would get the GTX 760 SLI, and see if the CPU is bottlenecking, if it isn't then you are fine, if it is sell it and get a i5 3570k.
