Bottleneck Question SLI GTX 560 Ti with my rig

AMD Phenom X4 II 955 @ 3.8Ghz
Corsair H50 CPU Cooler Push N Pull Duel Fans.
Corsair Dominator 8GB DDR3 1600(2+2+2+2)
MSI NF750-G55 Motherboard
Cooler Master CM690 Basic Case
Corsair HX850w Modular PSU
EVGA Geforce GTX 560 Ti (1.07v/920/2150)
Western Digital Black Scorpio 750+500+500 Raid 0
Windows 7 Ultimate 64-bit

LG E2350V @ 1920X1080


I'm looking to get a second EVGA GTX 560 Ti FPB to run in SLi with the the current GTX 560 Ti FPB that I have right now. Is my processor going to be an issue? This will be my first SLi build i've ever owned, any experience and or knowledge would be greatly appreciated. Thank you.

depends... a 4.+ ghz overclock and i think you'll be fine,

if there is a bottleneck it shouldn't be that huge.

One thing I forgot to mention is that I have an LG E2350V @ 1920X1080, and I game on that display settings. Would it make a difference?

no , resolutions only concern the gfx card .. lower resolutions use the cpu more but apparently .

3.8Ghz is as stable as I run with this setup. after 3.8Ghz I blue screen like a Smurf. Would a X6 1090T help alot? Would the X6 1090T Still be a bottleneck?

You will bottleneck because I bottleneck thats forsure_ Overclock it to 4.0+ and do some 3dmark runs you'll see that you get better GPU marks with the higher overclock CPU so this basically tells you that the 955x4 is bottlenecking the graphics cards_

Raise the CPU-NB to 2.6-2.8GHz and raise the CPU-NB voltage until you get stability.

going from an x4 to an x6 won't help_ since having 2 extra cores really means nothings in terms of removing CPU Bottlenecks_ plus it seems like a waste of money if you're not doing anything cpu extensive with the need of 2 more extra cores and Bulldozer is right around the corner =]

What voltages are you using to run at 3.8ghz? what are your current load temps?
