hm when crossfired some boards drop them both to 8x

I'm surprised that a 790FX chipset would do that though. I thought the whole point of the FX chipset was that they're performance boards for Crossfire. Might just be a BIOS setting... or lazy engineering...

Yeah. Foxconn too.

umm my slots are 16x

So are mine, but they go down to x8 with two cards installed.

Had a look at the MSI site...according to that both PCI slots are 16 lane...interested in knowing how this pans out as I have just purchased a MSI X58 premium board, tho i believe this mobo needs a bios update on install..

in hindsight i should have bought the Asus P6T
