heres a weird one for you guys. i just got a pny 6800 gt 256mb agp and put it in my aopen ax4c max board and it didnt boot. at first i thought the card was broken so i was getting ready to send it back. before i did tho i decided to test it on my other computer and it actually worked. now my ax4c max runs both an fx 5900 and ti4600 fine so i think the agp slot is okay. am i missing something?
