Recommend me a video card for Arma 2 (Maxed out settings)

Well,

The game I have been waiting for a long time is going to come out in 7 days. I know this is early to ask but I was wondering what your opinions would be on what card to play Arma 2 to its fullest potential?

I am worried that my 8800GTX will not do the job sufficiently (maybe it will be enough? prob not...)

I am not looking for the best card money can buy but something that will have excellent performance with Arma 2. (best bang for the buck maybe?)

Thanks again

You could try yougamers.com and try the benchmarking tool.

Well my GTX 260 gives around 15-20fps on max at 2048x1152 from the benchmark tool the ARMA2 demo has (AMD X2 5000 BE at 3GHz, GTX 260, 4GB ram and running XP.) But I'm sure if I turn it down to maybe 1080p or lower the settings it'd get better FPS. So take a look at that card. Or if you don't run high resolutions like 1080p or 1920x1200, then look at the GTS 250. If you want more power then look for the GTX 275 or if you fancy ATi cards, 4890 or 4850 x2.
