21RavageTue 1st Dec 2009 I currently have Vista Home Premium (64 bit), but we should all be running 64 bit systems by now, but whatever. I would recommend getting 64 bit if your computer has 3 or 4 GB of RAM. 32 bit systems have a harder time with lots of RAM (also commonly referred to as DDR or DDR2, etc.). Oh, and a laptop without 2 GB of RAM now adays, is a rip-off. Unless it is very cheap. It's your choice if you want to get Ultimate, but make sure it's extras are really worth the extra cost to you.Also, you should know that the basic does not have emulation for XP, but you can still run programs in XP mode, but it is apparently a pain in the butt to set up.
