The [H] gang also put up a very revealing article yesterday regarding gaming on the 64bit Windows OS, WinXP64. I'll go ahead & ruin this one for ya, too: unless you've got a game written for a 64bit OS, it don't make a damn bit o' difference. They did, however find out that driver support is not going to be too much of a hiccup.

"That said, it looks as though many gamers wanting to put those seasoned Athlon AMD 64 processors to use on a new Windows XP Professional x64 Edition, can do so without much fear."
