im lookin to spend about 350 on a graphics card or cards. im planning on buying an sli mobo so would i get better performance out of like 2- 175$ cards or one 350$ one?
he means companies like BFG and Sapphire and stuff,they aren't knockoffs,they are authorized to build cards because they usually use ATI's schematics and change it a little to suit their fancies.They are just as good or better than the name brand ATI's.
Agreed... I don't know of any knockoff's. I'm sure there are some out there, but they are rare and illegal as far as I know...
As for the question, most of the time, a single expensive card would give you better performace. Best would probably be to check into the cards you can afford. If it's between say a 2x7600GS and 1x7900GT, check some benchmarks.
