I found a 5750 but it needs external power too(http://www.ebay.com/itm/330776840394?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649), I don't have a spot to plug it into but if someone can find a pin out I can solder wires to the pins 
another thing is that , my motherboard is only 2.0 pci-e will it still work? I remember hearing a while back that it would just be slower (I was looking at a 4850 BC i could get it for $30)
