NEW Hdd, Windows 7 and Hopefully Steam too

Took the plunge, got a new 320 Gig HDD to replace the old 40 gig Xp one. Yes, I will be be installing my Windows 7 Ultimate Signature edition.
From what I understand that with some games you’ll more ore less have to set it as a permenant admin privs for it to work right, and sometimes using Xp mode works as well for it too.

Also got the S.T.A.L.K.E.R Shadow of chernobyl, Quake Wars Enemy Territory, Ghost Recon Advanced WarFighter, oh yea and Serious sam II (yay). Which I will test one by one as I install unto Windows 7 U/S.
