Dual X1900 in a G5

[Lord Zedd]

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?

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

 

[Lord Zedd]

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?

 

[Lord Zedd]

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.
