Sorry that i'm al little behind the times, little might be an understatement.

I need to upgrade my Vid card 2900xt cf as my second card died, to either a single 4870x2 or single 5870.

But my P35-DQ6 MB only has a PCI-e rev of 1.1.

I know that there is a small speed drop for the 4870, but will the 5870 be bottlenecked due to the 2.1 rev support of the 5870.

I have read that the 5870 saturates the pci-e on the P35????

Nope, going from 2.0 18x to 2.0 8x (which equals 16x 1.x) loses about 2% speed.
Hell going to 2.0 1x only loses 25%, it's amazing how well the card does with lousy bandwidth.

Definitely buy the 5870.
