I see your valid point on the Barracuda, small increase in price, large real estate gain. Currently I run a Seagate 250GB(232GB usable). at one time I had Crysis, Far Cry I and II, MW2, Sim City 4, MS Flight sim, etc and all of my storage and back up and still only used 130GB. So that is why I chose a 128GB SDD, and a 1TB HDD, intending to use the SDD for it's intended purpose, and having enough storage for the new games. I'm still running Win XP, I dont know what space windows 7 Pro uses. However... I believe that your recommendations will provide great results and compatability. I'm in

Should I increase the capacity of the SSD to 256GB?
