With my new computer I purchased Vista 64, but I also installed XP 32bit (and Debian 64bit). I'm using the integrated video card from the motherboard (intel G33). It is good enough for old games. It has drivers for both 64 and 32 bit OS's. The 64 bit bit ones are even 2 months newer than the 32's, but when I tried "Battlefield Vietnam", the crosshair wouldn't show up on 64. The 3D modeller Blender had issues as well. And it's been few programs I've tested. No probems so far with XP and 32 bit. So, for the time being I'll keep using XP 32bit, but I (still?) don't regret buying Vista 64. After all, my previous computer lasted +7 years.
