Then can you help me with this?
i would like to know how many FPS i would get on GTX 570 with AMD FX 6100 3.3 ghx six cores?
you would probably get around 55-60 with 4x aa look at some more specific benchmarks the reason you should usually go with the 570 vs 2 550s is that a single video card is gonna be more supported in most games as 2 cards aren't as reliable.
Really you should be choosing if 350-450$ is your budget between these:
FattyPatty Is right on the money. I can tell you for sure with out a doubt that the 550's in SLI and OC'd in BF3 tops would be 40fps, then when it heats up it drops to 30 to 35 fps.
I have two of them right now and I have tried BF3 which I can't play but one of my son's played on my rig. All the settings were on high then med. It heated up my cards to 78c.
The 570 will take just about anything you can through at it and still have good fps plus run 60c + temps. And the 550 ti you linked to what is so different about that card then the normal $129.00 card from newegg?
Heck I could buy a 560 ti for $199.99 with the rebate. I will link you to them as well. The 570 is the card to go with in my opinion. The third link shows a 550 vs 570 even if you double the 550 the 570 still out does it. Good luck to you.
I used to run two 550Tis in SLI, and then I returned them about two days later. They really performed poorly. Id rather have one of my 560Tis over a dual 550Ti setup. Trust me, do your friend a favor and tell him to save up or take the 550 back for a single 560Ti.
