I was reading an article at Anand.com,and it was explaining how DX9 versus DX8 bogged down certain video cards,Nvidia,and the 5900XT,in particular.Beings I have a 5900XT,I read on,and was astonished to see that by going to DX9,my card lost 68% of it's fps!These test were used with several vid cards,while playing the mother of all test beds Doom 3.I'm in the process of building a AMD puter,so I can try and get some better AH performance,and I figured I could probably salvage my vid card to go with new unit.I now have second thoughts,and I might try a ATI card for the first time.If anyone can shed some light on my findings,I would appreciate some comments.

P.S. Killnu,I used the Ti 4200,and with the new, better,5900XT my fps sucked.I believe Radeon might be the way to go.
