My build can be seen here: http://secure.newegg.com/WishList/PublicWishDetail.aspx?WishListNumber=7978688 plus a 7900GS overclocked and another 250gb hard drive I won't be doing much gaming, if any at all. My main uses are photo editing, some graphic design (logos, typefaces, non-3d), web design, music listening and composition, web browsing, pr0n. The idea of XP x64 being a little leaner appeals to me A LOT, but how is its stability....it's built on the server platform right? Thoughts? Why XP or why Vista?
