so 1 card->2 cards nets about 35% additional performance in Vantage. Crysis warhead is a bit less than 40% faster with 2 cards. 3 and 4 cards are not even worth mentioning.

Wow it takes 3 next gen cards to saturate the 2x8 pcie buses. Now the question is, are we cpu limited or is xfire scaling just not there yet on the 5800 series.

I'd imagine it's a combination of the two, with greater emphasis on the later. ;)
