    Is it possible to use two X1900 PCI-E cards in my G5 if I use the superdrive plug as the card power supply?

    Used 6600 video card prices are stupidly high, $150-250!. Why blow money on that low-end card when for the same $150-200 I can get another X1900 that has 2x the performance? :rolleyes:

    They will not work together. They will only be able to drive different displays, not give extra performance.

    Thats the idea. I've been wanting another card to drive my second display so the primary display can use the full power/memory of the main card.

    So in other words, a second X1900 will work in the 8x slot if I get a power source for it?

    Forget about it, I found the answer on my own. The card will work fine but it will be bandwidth restricted from 16x down to 8x.

    Instead of a second X1900 I've chosen to go with a flashed 7800 GTX 512. It has 2x the VRAM, 120mhz faster ram memory and 50mhz faster GPU than ATI's X1900GTO.
