Graphic Card Help, GTX570 or GTX550 TI sli?

[Ridalin]

I've never Sli'ed or Xfired before, so I have absolutely no Idea what they performs at.

I was wondering if a Sli'ed GTX550Ti would be better then a non-sli GTX570?
And what PSU Voltage should be used?

 

[Roark]

From what I can tell the SLi-550Ti uses more power and less performance than a GTX570.
That being said the differences weren't enormous.

I'd personally get a single GTX570 just so that in the future I could add another one for a greater boost in performance.

Other 570s suggest a -minimum- 550w PSU with 38A on the 12v rail.

Single GTX570 is the way to go.

Yeah, I was going for the 570, but seeing the 550 for only $140, I had to ask.

I have a 750W PSU, so I'm all set there, Thanks for your info and help!
