Looks like I'll be running an OS 3.9 system if I buy one of red's 4000t's since gaming and whdload is my main concern... Don't know if the 4000t is worth the investment at this point, as I could probably get a 060 or PPC accelerator (already have a Bliz 030) for one of my 1200's cheaper and have almost as nice a machinbe as the decked out 4000t with the PPC card my friend gave me. Decisions, Decisions...
