I mainly will use my new system for internet, email and some light gaming. It will have 6gb ram, an ATI Radeo 4870 1gb video card, an x-fi Titanium PCI Express sound card, Asus P6T motherboard, and a core i7 920 cpu. I'm a bit out of the loop on where things stand today (it used to be that people had some compatibility and driver issues with Vista 64) regarding Vista 64. So will I have any problems going with Vista 64 so that I can address the full 6 gigs?
