i have a sht computer case reight now, stock. im going to be buying a new one, and i just cant wait to install everything into it. getting a new 750w psu, going to slowly upgrade the pc one part by one, i just got the sapphire radeon 5770 so ill be installing that. but when i put all the parts in the new case, im going to put both gfx cards in, the one i have now (shit) ati radeon 2400 hd pro and the one i just got sapphire radeon 5770. would they work together? itll be a waste to throw out the 2400.
