Solved Advice with crossfire

[Marshall Moore]

I have a Sapphire HD5570 card. I want to buy another one and try running 2 GPU's. I haven't done this before. Is there any thing I need to know first. Also how do you go about setting up the PC to run in crossfire mode? My MB is crossfire compatible. Thanks

All things considering you would be better off getting at least a HD 5770 (or HD6770, its replacement) than running two HD 5570's in Crossfire. One 5770 is faster by quite a bit than two 5570's,

that and you avoid any of the hassles that can come with running multiple cards (same can happen with SLI).

Thank you

You may be right. That may be best. I have a 500 watt PSU. An additional card might require me to purchase a new PSU anyway. So the price of a crossfire ready PSU + another 5570. Greater than HD 6770.

Thank you
