Here's the scenario- I've got a Winfast NF4SK8AA-8EKRS motherboard, a gig of ram, opteron 148 cpu. I roiginally had a 7300gt in it. Deciding it was time for an upgrade I bought an XFX HD 5750, I fitted it and plugged my monitor in, however there's no output to my monitor. Anybody know of any problems with the 5700 range or is it a dud card?
