Whow! that's a fast answer, thank's bro, both in PCI-e, so the X1600Pro would be the best choice then! OK I'm going with the X1600Pro It is even cheaper :lol: :lol: :idea: .
Being that it's PCIe, check out the price of the X1600XT it's worth a $20 premium, but if you're ammenable to nVidia then the GF7600GT is nice @ $150 now, and then if you prefer ATi I'd suggest checking the prices of the X1800GTO where you are.
There are lots of options, and IMO the ones you picked are a little low on the list. On NewEgg you can find the X1600XT for a great price, the GF7600GT for a great price, and the X1800GTO for an ok price. They are progressively more expensive so depends alot on your budget of course.
Anywhoo, at the very least it's worth looking into the price of the X1600XT.
