Hi, I have a Gigabyte 2AC8 which has 1 * PCI Express x16 (2.0). I am wondering if I buy a 7870 which is a 3.0 card, will it work fine on my 2.0 motherboard. I'm pretty sure its backwards compatible and I read a few threads here that says its fine, but just to make sure I'm going to ask
The better brands are Corsair, Seasonic, XFX, and some Rosewills. You really are over doing it with a 700W since you can't add a 2nd graphics card to that board. Any 600W - 650W would be more than enough.
