Easiest way to find out is to pull task manager and msi afterburner, if your CPU is 99% and your gpu's aren't being fully stressed with vsync off then its very likely its caused by CPU bottleneck

You could really do with a 6core i7 to help with the bottle neck, 970 upwards

This. Only you can say for sure if you have a bottleneck.

Check your GPU usage under load. If GPUs will max out under load without the CPU being at 100% then you're just fine. If your CPU maxes out before your GPUs do, then you're CPU is bottlenecking you.

OK, I will pull up task manager and check it out when I go home. I know in Battlefield 3 beta in MSI afterburner I was seeing mid 80's GPU usage, I have a small cpu usage monitor on my side bar and i remember seeing it at what looked like 90% usage on the highest core, but i will check in task manager when I get home and test it in various games.

And yes, I am waiting till socket 2011 before I think about upgrading my CPU.

That I think 1366 is better than 1156 for quad sli setups due to the CPU riding on the PCIE lane on 1156

I would try a different game, bf3 is still in beta so isn't really trust worthy for what you want to figure out.

Maybe some more like bc2, arkham asylum, metro 2033, crysis 1 or 2. Anything with a final release that we know will stress your system.

Even if there is a bottleneck if you sell your current CPU it wouldn't cost too much more for a 970, they pop in at the marketplace here and there

Just remember to leave vsync off, or your wasteing your time lol

Sorry for the off topic, but a 60Hz 1080p monitor with that setup? Massive waste of firepower if you ask me. You should get yourself a nice 2560x1600 or 120Hz monitor!

Yes you're being bottlenecked! Now give me one of your 590s!

Hahah, jk. But as TheReciever said, that's the only way to find out. I wouldn't think you'd be bottlenecking but you never know.

PS: You should definitely get a 120Hz monitor. Everything would look soo much smoother.

You are definitely being bottlenecked!

Also, that setup is WAY overkill for a 24in/60hz monitor. Get a high res or 120hz monitor ASAP.
