Hello, I have a Fujitsu T900 running Windows 8 with a first gen core i7 and 4 GB of RAM. It has a mPCIe for the wireless I think and a Express Card 54. I want to get a GTX 760 and am wondering what setup I would need and which would be better: 1.Opt or 2.x speeds? I'm confused by a lot of what's said in the introduction on the first page, so forgive me if I don't know what I'm talking about.
