Hi mthank you all for the Info..I did get the new PS 750W.. I truly have to admit that the computer, i think, is better..The screens are brighter and I think the speed is better..A good investment...
HOWEVER, I heard from XFX and this is what they said!
This card requires a 6 pin poiwer connection that a 300W power supply will not have. We recommend a 400W at minimum and it must have the six pin PCIE power connection. Some motherboards require a BIOS update to work with the new PCIE 2.1 cards. The entire 5000 series line is PCIE 2.1. The problem that we have seen is that because many of these boards are older and the manufacturer of the motherboard had dropped support for them before ever updating to include support for these upcoming features. I am yet to see a single socket 754 motherboard work with a PCIE 2.1 card. You can check the motherboard manufacturer`s website for an update but I feel that it still will not work with this motherboard and would be severely bottlenecked by all of the other hardware that is in the computer. Thank you. Mark
