Nvidia and Biostar compatibility

No. If it has a PCIE 2.0 16x slot the nVidia card should work. If it's a 7000 series+

Err from 2008 onwards i had lost count the amount of DIY PCs i rigged up with AM2+/AM3 Biostars and GTS250/GTX 260s in there  

Hey man thanks, I remember reading in a forum about some incompatibility but it may have been just one guy with a bad board (TA790GX A3+) or graphic card.

You are welcomed ^^
