maybe , but his card is only DX9 anyways... so overall i would tell em to stick with Windows XP SP2 as it's stable and everything is supported... with Vista it's all a gamble... but it's getting better lately.. but SP1 should make it a fairly safe bet by then.

but even then, theres not much real advantages Vista offers over XP anyways (plus not to mention Vista is generally a ram hog)... so i say stick with XP for a while cause it's supported to like 2012-2014 from what i heard anyways... and by then the next Windows OS will be out.
