I'm an owner of a motherboard (Asus P5K)with Palit HD4650 (1024MB)video card. I am planning to purchase an identical video card (Palit HD4650) (1024MB) card and have it operate in a crossfire system, is it okay?

Should n`t be a problem, although the second (black) PCI-E slot will only run in X4 mode with Crossfire enabled but I doubt a HD4650 will be fast enough to saturate the bandwidth.
Although I am wondering why you are going this way when a single HD4850 would give similar performance without the inevitable Crossfire penalties?
