my brother-in-law is getting this computer and I was wondering about a video-card. I wouldn't want him to have to change the PSU, but I do want him to have something kick-butt for Vista. (he hasnt had an upgrade for 5 years or so,.. he's still running a 3.0ghz hyper-threaded pc with 1gig and a 9800pro.) This new one has PCIe 16x, and one PCIe 8x I dont know the size restrictions on the case, is there any way to figure this out? A hightech web site that allows you to put in your case size and PSU restrictions and find a videocard that way? Or what kinds of things should I consider?
