what about brands

i dont understand the diff brands of nvidia (pny,bfg,apollo.asus, etc) why is this cus ati just has ati cards. is there a certain kind of nvidia card that is better. please explain.

from Tom's Hardware Guide: "NVIDIA is a chipmaker only, focusing its attention solely on designing and producing graphics processors, while leaving the production and sale of retail cards to its board partners. ATI, on the other hand, is quite active in the retail market as well, albeit only in the United States and Canada. Its cards are usually designated "Built by ATI", while those produced and sold by other companies are "Powered by ATI.""

^great source of information

Yes tomshardware is a great source. But take into mind that Anet worked with ATI in the game development so this game is optimized for their cards.
Other games work better with Nvidia cards.

Dog eat dog world.

if you are thinking of buying a card also chech some reviews of that manufacturers card as well as how long the warranty is along with how long the company has been in business

the warranty on my leadtec card is 3 years and they allow overclocking as well
