I have a HD6770 and get quite decent frame rates (varies between 30fps in very dense areas to around 70fps).
I have heard that FSX is CPU intensive (is that correct?) and so more money should be invested in the fastest CPU you can afford rather than the video card ie you get better results from a faster CPU - is that correct?
Speed isnt that important. Get a quad core processor and set the right affinity mask in your fsx.cfg file for the best results.
