Mafia 2 and my 4870x2

[MrMunch101]

Hi guys, a quick few questions on games and some hardware issues as well.
I am running

Rampage Extreme 2 mobo
i7 920
1600mhz DDR3 Ram
4870x2 Graphics card
850 watt psu

1. When I was running the mafia 2 demo maxed out I was getting some terrible fps like 10-20. I am using catalyst 10.4. I would have thought my GPU would have a lot more juice.
2. I was thinking of upgrading my GPU and maybe get another card to put in crossfire, any suggestions

As always with new games and crossfire/x2 cards, try fiddling with Catalyst AI.

First try disabling it (this turns off the 2nd core, so you are running in 4870 normal). If this shows a sudden boost in frames...
I didn't have any issues with the demo on my i5 750 + 4870 512mb @ 1080p AA off, physx off.

Switch physx off in the menu.
