What is the best Nvidia Graphics Card and what is the best ATI Graphics Card?

ok, thats tough, but i'll but into 2 categories:



SINGLE GPU'S:

Ati: well that would be the HD4870, which cost less then the gtx260 and out performs it in most tests



Nvidia: the gtx280, this card is a monster, but will burn a hole in your wallet, it's currently the fastest single core gpu.



DUAL GPU'S

Ati:the HD4870x2 is a nice card, unlike Nvidia, this card has one PCB and has both the cores on it. It's ATI's fastest card, and depending on the application it beats the gtx280 (some games don't support crossfire/sli)



Nvidia: well that would be the 9800GX2, nice card but is a lil slower then the 4870x2 though...





NOW, then pricing of these cards range from $300 to about $500.



Their is no doubt that Nvidia's gtx280 is the fastest single core gou ever made for mass market, but the dual gpu's are where the performance is at|||The best is meant by the most affordable or the highest performance?



I dunno which so I google those and found these
