i have the xfx hd 5770 and it is a pci-e x16 2.0 card. i was looking on newegg today and there are some new cards that are 2.1. what is the difference? if my motherboard is 2.0, will the 2.1 work? will there be a performance increase/decrease? i am looking to crossfire my current one with a new one: any troubles there?
