ok, my brother and i can't seem to agree on this and Google is not helping me at all. I say if i get a 650W PSU, thats good for the 8800 GTS. but he thinks it needs to be a 750W to 800W PSU. I think thats over kill and i really don't want to spend money on something i really don't need. (or in this case money i really don't have.) so does anybody know?
