Hello,
Hi does anybody know if i would be able to xfire the ati 4870 with the TA790GXE 128M mobo because the manual says at 1 stage it does support xfire for that card and at another stage it dosnt support it in the same manual!!:(

You can crossfire a dedicated video card and a motherboard but you cant crossfire a 3 series and a 4 series.

Evenm if you motherboard had a 4 series ATi graphics card the 4870 would be downclocked to the performance of the onboard card and you would end up losing performance. It would be better off running the card by itself.
