Hmmm....
The display 3 x 23 "ACER A231H Eyefinity setup 2328/1280 display is a show stopper.
Do you use three screens for IL2?
Do you want to keep on using it when you get your new graphics card?
If yes, then you need to stay with ATI and Eyefinity.
The alternative: to buy a Matrox TrippleHead2Go costs extra money thus excluded due to your initial parameters.
I can not give advice on ATI cards as I am not knowlegeable enough (although I will own one soon).
For NV buyers I always recommend:
Low level upgrade: GTX560ti 2Gb VRAM
Med level upgrade: GTX570 2,5Gb VRAM
High level upgrade: GTX580 3Gb VRAM
So probably you need to look for the ATI equivalent to these cards.
The new Radeon HD 7970 (HighEnd card) is the best card today but very expensive.
The new Radeon HD 7950 (HighEnd card) seems to be very good but you have to read the benchmarks yourself.
If the 7950 fits your budget then you are going to be happy.
If you are happy with the 7950 you do not need to read any further. If you do, complexity and waiting kicks in:
The new Radeon HD 7770 & 7750 (Mainstream cards) are coming but, these are "low performance cards"
The interesting cards are the new Radeon HD 7870 und 7850 which will be Performance cards thus will be between the 7970/7950 and the 7770/7750 in terms of performance.
Since there is very little information on the 7870/7850 you need to sit and wait...
This is how it is supposed to look like: The 7000 series vs the 6000 series. The percentage% is according to ATI's information regarding te performance of their cards.
