2nd this above. The 6850 is only slightly more expensive than a 5770 and is a much wiser choice.
save just a little more and get this:
See review here of the card overclocked to higher than stock 6870 (and close to overclocked 6870) levels:
Do NOT get the factory overclocked model here:
The factory OC model doesn't allow voltage change as it has a different VRM. The "standard" or "vanilla" model is the one in the review, the one I have, and is a wonderful card for the price.
As far as power supplies, any decent 650watt model should handle crossfire 5770's or 6850's, though a 750watt model is better for peace of mind.
Corsair PSU's are usually on sale/discount, or Antec True Power New models are a good buy too.Edited by willibj - 1/30/11 at 6:40pm
