  1. According to the spec page on TigerDirect that PSU has 650 watts (54 amps) on the 12V rail, so for $10 more I'd much prefer a true 750 watt PSU: XFX 750W $140 which will definitely be enough for two 5870s.
  2. ok ill go with that then i guess. does it matter if it is Crossfire certified?

    What kind of performance do you think i can expect while playing games at 1080p with this system?

    Good PSU. Ugly color though :X lol
  4. No. Generally the Crossfire cert isn't necessary. The cert is there to tell you that ATI has tested the specific PSU and that it does meet their standards. This doesn't mean that it won't work for you; or that it won't support a crossfire configuration. The big concern about PSU is the amperage output on the +12v rail(s).

    As far as performance, well that's a little complicated. Some games are heavily reliant on CPU/RAM configs, while others shine from better GPU/multi-GPU configs.
    Check out this link for a very detailed explanation. While the CPU and GPU are different than your picks, the info behind the testing is what is important.

    Not really. BTW the specs for the XFX on TigerDirect aren't accurate, as it has two 6+2 pin PCI-E connectors, which is what you will need for two 5870s.
    You should be maxing quality settings in most games and getting very playable framerates.

    Strangely enough I don't mind the colour when looking at it on a webpage.
