will 2x GTX 580 bottleneck i7 950 oced

post #1 of 31
Thread Starter 
Pretty much what the title explains. I am thinking of getting a new psu + 6 more gigs and a 2nd GTX 580. My i7 950 is overclocked at 4.2Ghz and is very stable. Will getting a 2nd GTX 580 be ok to get or should I just sit on the single. I play at 1920x1080 and I am going to be getting a 3D ready monitor when Viewsonic releases this one:

Not at all.

I had two overclocked GTX480's with a 950 @ 4Ghz. No bottlenecking problems at all.

Ok that is good news. Call me stupid but I am a complete newbie when it comes to SLI. Does the second card have to match the same exact specifications as my current card? At the moment I have my card Oced, so will my second have to be Oced at the same rate?

Yes. your second card must match your current cards OC. AFAIK you cannot run one overclocked and one stock. you have to OC them the same. or keep them at stock settings.

no, the faster card clocks down to match

If you want it to run at the same speed yes, but if it can't then the faster one will downclock to match the slower one.

You kinda gotta define bottleneck for an accurate answer.

If you simply mean not let the most performance the two 580's have to offer, show in FPS...then I'd say probably yes. That answer is based off that [H] review of the 2 (then 3) 580's vs 6990+6970 first with i7 930 (which bottle necked the 580's) then i7 2600k (which released a large amount of FPS)

However, with only 1920x1080 it will be massive overkill FPS wise so I'd look at a larger resolution monitor first/as well.
