Hi guys, im looking to upgrade my gpu. Im going to spend all of my money on a 7970. So right now i have a Pentium III-S at 1.32 GHZ. I also have a 305 watt power supply and im wondering if this psu would be overkill since i heard the 7970 is very energy efficient. Thanks for any help
You will need a new power supply first to even run a 7970.
But to answer your question directly, yes oh horribly yes...
You need a new cpu/motherboard/ram/power supply BEFORE you even think of a new video card.
