Hello everyone. I have a question about what is better pci e 2.0 or 3.0 for my own gaming setup. I have 2 msi gtx 570 twin frozr iii's. I am looking for a new mobo to give them a little air flow. One board I looked at has pci e 2.0 and other 3.0. I was wondering if I went with 2.0 would my sli be hindered at all? What should I do?
