First and foremost, find out the exact model number of your machine, and check the manufacturer's site to see if Windows 7 32/64 bit drivers are available. If not, then don't bother wiping out Vista. Windows 7 is good at obtaining drivers from Windows update but the process is far from perfect. You will not be able to get optimized performance without specific drivers. Few people realize this but within the PC world, drivers make or break your experience with the machine. If you need any one-on-one correspondence regarding this, please feel free to mail me.
