post #1 of 14
Thread Starter 
Hello I'm looking into buying a second EVGA GTX 660ti for sli. I have 2 questions about this, my mobo is a Asus Sabertooth Z77, will this run them ok or should i not even bothing with the x8 timings? second is how much wattage should i have? I have a Corsair AX 750 and I am not sure if it would have the wattage to handle that. any comments would be much appreciated. thankyou:)

you will be alright, a 750w psu will be more then enough for 2 gtx 660ti in sli. look at my sig, I have 2 gtx 680 and they run fine on my tx850w psu. I could even run them with a 750w psu, so you good to go. you have nothing to worry about thumb.gif.

Your motherboard runs SLI pci-e 3.0 x8 speeds thats more bandwidth than you will ever need with those cards. (Only does 3.0 speeds if you have an Ivy Bridge CPU)
660ti sli scales great. Almost 2X performance in some games. And that is with old drivers. http://www.overclockers.com/evga-gtx660-ti-superclocked-sli-scaling

123fps on BF3, very nice! You might be looking at a 120hz monitor next thumb.gif

your cpu can run 4-way SLI gtx 680s with no issues.

so yes everything will run smooth as butter!! just make sure good ventilation in your case and your good to go!

Sweet! I'm going with a switch 810 so watercooling will come in the later years. i went with a 660ti FTW sig 2 with the 680PCB biggrin.gif THE THING IS MONSTROUSLY HUGE! It's my first GPU and i thought it would be half the size XD thanks again biggrin.gif

I wouldn't say that. 4-way SLI always has issues, even with my 3930k @ 5ghz.

Just like to say I run two 660ti cards. Scaling is very good. Currently enjoying Farcry 3 at 60fps, no drops.
750w psu.
