4870X2 and a 4870 on My MOBO?

hello.

I have an Hp XW4400 Workstaion.

It has 2 Pcies, But they are very close, and It is an old 975X bases mobo.

I was wondering If I could stock a 4870X2 to go with my 4870.

Would it work?

Would it run at 8x 8x or 4x 4x or 16x 16x?

And would a QX6700 2.66ghz Intell Core 2 Quad Extreme Bottleneck a 4870 Tri?

The QX6660 will bottleneck your GPU's at 2.66 GHz running a "tri-crossfire" at high resolutions. You will need to overclock it to at least 3.4 GHz for better performance.

Your cards will run at 16x, 16x since it is two motherboard PCI-e slots. The 4870x2 is a one slot card, so it will run at 16x and the 4870 is a one slot card, so it will run at 16x. If you were running three separate 4870's, they would run at less speed, as it is using three PCI-e slots.
