it conserns to VGA cards ... NEW 5000 series are 2.0 or 2.1 not higher not lower ....so for see them geting matched better on mobos .... we see if our mobo can support them ...as our friend said ...1.1 or 1.0 mobos can only accept 2.0 VGA cards ...2.1 maywork incorrect . so first find out what is your PCI slot version ..then go for 5670 or something else .
