I admit to some confusion. I have an E6600 CPU on an ASUS P5B Deluxe mobo and 4 GB of memory. Can I install Vista 64 and if I can are there any things I should be conscious of before doing so like my X1950XT video board won't work or I need to be a glutton for punishment. I'll be using it for games, mail and web surfing when I am sitting at the keyboard and when I am not it will be running SETI, Einstein, Rosetta, etc.
