I'd also like to point out the "best case scenario" for price... If you only see 1 card at 509, but all the others are above 509 it makes it sound kinda biased towards showing the best P/P ratio for the nVidia cards. Same goes for a P/P on the Ati's, but they're more stable now (I think).
Also, I would've loved to see more games out there and different configs (maybe an 3way-XFire with a Phenom II) just for the WHOLE P/P ratio, but then again, that would almost be a Builder's Marathon, heh.
Cheers!
