Thanks for the posts here.
As soon as I fired up BOS I figured it was time for a new card, running an Intel i7-2600k at 3.4 Ghz and a GTX 260 vid card now(says 896 Mb memory) and getting at best 40 FPS in BOS with lowest settings...... never less than 60 in IL2 46(usually over 100)
Just ordered this at $329:
