Looking at this corsair 750w, more expensive than I planned but I underestimated the importance of the PSU.

Specs read it maintains 80% efficiency even at 100% load. Seems like the sort of thing I'd need. Could you guys look at the specs and see if its suitable for an SLI system.
In other news, Sound Card I picked is X-Fi Xtreme Gamer

Says theres a fully Vista compliant Music version... will this gamer one work fine with Vista? No mention of vista compliance in the specs.
