Just want someone to confirm what I think i remember reading somewhere before I purchased my deluxe - I know xfire drops the pci-e lanes down to x8 but If I dont use xfire they should both stay at x16 right?

Reason I ask is I plan on picking up a 4870x2 in the next couple weeks (pending good reviews) and since 8800+ cards can be used for physX now, ill just make my gts320 into an overpowered PPU running in the 2nd slot. However if just using a second card drops both lanes to x8 I may have to re-think the ppu (which only effects a few games, none of which i currently play...) as i think that could make a big dent in the 4870x2's performance since thats a lot of processing going through that slot.
