I have all my ram slots full with 1gig sticks.. I got 4gigs of corsair ddr2 xms2 memory. It looks like I need to start shopping for a second ati video card. Guess I will upgrade to vista tomorrow. What is the difference between the 32bit and 64bit versions? I have the 32bit Home Premium. My two 22inch Ultrasharps are on the way so I better get looking for a video card.
