Which is the better Gpu of these 3?

Solution
They are all 280X cards, so they will all perform the same(ish). The higher the clock speed, the "more" frames you will get. If the slowest card is clocked at 1000MHz, and the fastest is 1100MHz, then you might see 10% better scores in game. (It doesn't directly translate like this, but I'm keeping the math simple.) So if in a game you get 30FPS, the faster card might give you 33FPS. (Or 60 vs 66.) Seeing as you can adjust the clock speed yourself, I feel it's pointless to worry in this case. They are all new and have a 2yr warranty, so you might as well get the Vapor-X card. (last link.) If you believe in rebates, I'd get this card. Similar price though a bit more out the door, but it's a better performing card...
