Is the GTX 580 FTW Hydro Copper 2 just as faster or do I need to sli something?
Considering the GTX480 was around the speed or faster than the GTX295 and the GTX580 is faster, I think you are all-right.
For example
That's what I was looking for THX GaiaHunter. What site is those second and third pics from?
The gtx 580 hydro copper 2's are just like regular 580's except single slot cards with (obviously) water cooling, sli works fine as does tri sli. Not sure about quad sli never seen it with hydro copper's.
