i say get what you got on that list. i got the 9400GT 1GB for HDMI for my dads voip computer (lol?) and my dads HTPC that i also built has inbuilt. i gotta say that the 9400GT will play games fine, i got a GTX 260+, 2 x 2GB OCZ Reaper 1066MHz DDR2 ram, 500GB Seagate, PATA DVD-DL drive, CM 690 pure black case and that actually runs fine with a Thermaltake OEM 430W psu lol, oh and a E6850 @ 3.7GHz.
hey tys i can sell you my C2D when i get a quad for this rig (ill get a cheap Q8400 or something)
if you wanna know the full specs of tysons rig it's a ASUS P5P800, 2 x 1GB DDR 677MHz ram, 40GB hdd, Xion case (first version), Pentium 4 3.0GHz stock, stock cooling fan, 2 x 120mm fans (1 rear 1 front)
i know because i built it
than i sold it to tyson after owning it for a few years the original 250GB sata hdd broke so i put a 20gb hdd in it, that broke so tyson put a 40gb in it.
tyson i can sell you my Thermaltake 430W psu when i get a new psu, it runs all the above hardware i use just fine.
