Uh is it only me but no one has figured how much cpu speed/power these new cards need to run at full power?

The 8800 series and 3800 series needed around 3.0 ghz it seemed so what does this new round need?

and some of these leaked reviews of the 4870 dont make sense they make it out to be slower then the 4850 which makes no sense. I think the ones that put it between the gtx260 and gtx280 are the most likely. And if I must say so myself the ones I hope to be real.

I'm to poor to have to uprade to a nehalem at 3.5 ghz or something to pull there full potential...Not to mention the bugs the new motherboards and cpu's will likely have.
