Good point about the Catalyst needing Advanced. It's almost second nature to me now but for someone new to Crossfire it could easily be overlooked.
(summary of long post at bottom!)
I'm still slightly concerned about the cpu temp. Google suggests that 61C is the max you should let a 9850 reach. AMDs really don't like high temps, and yes, the stock cooler is that bad.
If the cpu is going over 61C, then it will probably be throttling itself which would definitely cut your fps.
It might be an idea to tweak your settings. I don't run mine at FULL High, but it's High enough for it to still look good but run smooth.
I'll do some benchmarking for comparision:
Good looking, playable settings (what I use):
Average FPS: 59.73
Duration: 37.64 sec
CPU Usage: 43%
System memory usage: 73%
Video memory usage: 36%

Shadow Quality: Off
Reflection Resolution: High
Water Quality: High
Texture Filter Quality: Anisotropic x16
Night Shadows: Off
View Distance: 40
Detail Distance: 60
Vehicle Density: 50 (added because it's not on the list for some reason, this will affect CPU a fair amount)

It's also worth mentioning that the benchmark is not very indicative of actual in-game performance. Despite getting 54fps on those FULL VERY HIGH settings, in-game it would probably be playable but there'd be frequent noticeable slow downs. For this reason I prefer to drop some settings and have a smooth game.
Settings I advise you tweak:
- Shadows (these kill it for me in-game (not benchmark), I can play quite happily without them)
- Distances (find a long road with building on either side, tweak the distance and see how noticeable the change is.
- Vehicle density (for a stock cpu this may make a sizeable difference, not 100% sure. I play at 50% and there's plenty enough cars to steal/crash into)
That said though, I'm still thinking it's cpu, so Shadows and Distances might be fine for you because you're on a lower resolution.
Summary! - I think it's CPU temps/throttling/not enough GHz. Might be worth tweaking some graphics settings down a bit but at low res I would think the 4870x2 could handle them.
