Hi guys, I'm buying an HD5850 tomorrow, and the store I'm buying from has 2 different HD5850's. One has the brand of Sapphire and the other Asus. When I compare their specs I see that Sapphire has PCI Exp 2.0 and the Asus PCI Exp 2.1. Asus is like 20$ more expensive. Other than that there's no difference but the shiny design of Asus.
1. What's the difference between them if there is one?
2.If I buy the Asus one, will my motherboard also need to have PCI EXP 2.1 support? or 2.0 motherboards also support 2.1's? Sorry I'm kinda newbish here.
