"Cards from two separate retail companies will work together in SLI mode,
but they must be the same GPU model (e.g. G70, G73, G80, etc). The cards may
have different BIOS revisions, different default clock speeds, or even
different memory sizes. However, the fastest card - or the card with more
memory - will run at the speed of the slower card or disable its additional
memory."

It's the CROSSHAIR: 'CrossHair Motherboard (Asus-CROSSHAIR) - Compare
Prices | Tom's Hardware'
(http://stores.tomshardware.com/searc...st=product_tab)
It has 2 PCI-E x16 slots but i'm wondering if the two gpu's need to be
exact matches inorder to work or can they have the same frequencies just
different models [8800GTX(overclocked) with a 8800Ultra(stock)]
