Well, today i'll be returning the 6870, it isnt performing like i ifgured it would and i found a site that shows the performance of this card compared to some others, and its odd how one of their 58xx cards outperformed mine..... So im getting the 6950 with 2gig ram, so this should be flying pretty well.
I also decided to do a mini pc upgrade, bought an i5 quad 2500k 3.3ghz cpu, 16 gigs ran, mobo, and a sata3 drive for the OS, so this thing should be humming along with no issues and i can retire this other hardware into my server and throw away the P4 system.
