Hi!
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?

Hi, im planning to do the same thing as JUNIE and you mentioned crossfire penalties. Could you please describe the penalties of using crossfire? Thanks

I would either step down to the HD 4650 512MB or step up to the HD 4670 512MB.

1GB of VRAM for a low end video card is simply a waste of money.
