Upgrading

[empier1988]

Looking at upgrading and had a question...I have a 600 watt psu wondering if thats even enough to do a crossfire setup (I have never had a 2 card set up)

Which one would be better

PowerColor HD 6870 in Crossfire

or

single evga 570 superclocked

Q1: It depends on your rails. It should do fine if you don't have alot of stuff.
Q2: 6870 considering there is the new Drivers lately 11.5 and it makes alot of AMD/ATI faster. ( About 20% )

The easiest way to find out is if your power supply says SLI ready or capable. You didn't list the psu ,cpu ram or motherboard for us to see. Those are important as well in determining if you can SLI. The 600w might be border line ok , of course it would definatly work if you had a 700 or 750 Maybe even a 650,

without knowing about the PSU its impossible for us to say.
