Hi folks. I read a lot of requests for opinions of video cards for use with Flight Simulator. Tom's Hardware has what I found to be an excellent chart listing technical specs and FPS rates for a variety of chipsets (tested with a variety of games...some graphics-intensive, some not so much, so you can get a solid idea).
The link is:
When looking at frame rate comparisons, I used the "Quake" info for general First Person Shooter gaming info, and used the "Aquanox" ratings to simulate what I might get with Flight Simulator (because of the different environments I understand that game has). Since I've now purchased a new card, I found that the guide was, indeed, helpful and I'm very happy with the choice I made.
Hope this is of some help to folks.
