Update :
Well, i talked to my brother, and he payed $200 for the 9600XT...about the going price. Bestbuy had a sale for the 9800Pro 128Mb for $200 (after 50 mail in rebate). Still need to take the other one back tomorrow, but got the 9800 and put it in. Hot Damn did it make a difference. 3dMark03 scores went up from ~3800 to a happy little 5900. For the same price, im glad we went to the effort of returning and buying teh 9800.
Also, hooked up that serial ATA 160GB drive. Haven't backed up and taken out the other one yet, but got this one in and partitioned. Went to format it and damn near pissed my pants. Did a straight out format (not quick format), and the entire 160GB was done in less than 10 seconds! Put a 20GB in my dads comp on the good ol EIDE, took several minutes to do that one, and it was a fraction of the size of the SATA.
Hafta say, now that the video card swap is dealt with, i am damn happy with the new system
