Purchase a 64-bit version of WIN 7 Pro (this is non-OEM so it is legal). This one runs around $90.00, but the $70.00 versions tend to be OEM. You could get away with it, but it wouldn't be legal. If your computer is compatible with a 64-bit OS, you could then use the RAM you purchased and a ton more. I would say 12GB or more.
