Hi! As you can see in my sig, I have a XFX Radeon HD5770. I'd like to think about adding another HD5770, but I am not sure whether any other HD5770 will do or do I have to get the same XFX one? I am asking cause the case is kinda small and the available space in there is not what you'd call plentiful, so I wouldn't want to put another two-slot video card in there. I would take a one-slot gigabyte card and put them both together. will that work? The XFX card is not really OCed, so it wouldn't bring the XFX card "down". I have come to think that it's just XFX-themed and nothing's been really changed...
