Good point.. Plus it will give you a little more room to overclock the Cards
But I think the Premium they are going to tack on Defeat the Highier Overclock..
Odds are the 6800GS 512 would cost about as much as a Plain 7800Gt (which would perform better when overclocked)
and the 7800Gt 512 would cost more than the 7800Gtx... Just a thought
