Yea, price range is the question
My first advice, though, is get rid of that 5200 as soon as possible.
I used that card for a year, and had to stay away from IL-2 for that time, since it ran shall we say less than well on that card. Updated to a 6800 (1.5 years ago), and haven't had any problems with my games since. I'm sure you can get an even better card for a very reasonable price now.
