I am finally upgrading from dual to quad core so I am about reinstall windows Vista. My PC is used mostly for gaming. What is the best configuration for a fresh Vista installation. I have 2 hard drives, a 1TB and a slightly slower 650GB. Do I setup the larger drive as my main operating system drive with the swap file on the second drive. I am not sure which drive I should install Steam and other games to. Currently I have games installed in both drives due.
