I have a GIGABYTE GA-Z77X-UP4 TH LGA 1155 Intel Z77 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard running win 7 64 bit and I am looking at new egg for controllers and I see some cheap controllers but they say PCI Express x1 or some say PCI Express 2.0.

they look like they go in the same slot so what's the difference? Looking at the MB it says there are three PCI Express x1 slots. I know you are thinking to yourself "just buy the one that says goes in your motherboard" but I am curious as to what the difference is.
I'd like to add something to the PCI Express 3.0 slot but the cheapest thing I find is this for $300

Any brilliant thoughts?
They are the same. PCI-E x1 is the slot type PCI-E 2.0 is the revision.
