Re: Are these graphic cards compoatible with my PC?
you have the PCI-E slot on the motherboard and more than enough of a watt limit on the power supply.
the only thing left is the PCI-E power connectors from the power supply. It appears you have at least one 6pin so the 7850 will work.
if you have two 6pins then the 7950 will work.
careful tho, take a look at how many 6pins, 6+2pins (6 or 8 pin), or 8pins PCI-E connectors your power supply has and then look at the specifications of the graphic card you wish to buy to make sure you have enough of the right kind. for example, I noticed a 7850 that takes two 6pins instead of one 6pin.
