Anyway, if I do get a new graphics card, I would appreciate your opinion on what is likely to give me as good performance on Linux as on Windows
It will be a long time, if ever, for the two to perform the same. Any game that uses dx10 or 11 will be missing any features or options that require them when playing in Linux because they are not yet supported.
If the bar you have set for games is to play the same as windows, then you may be happier in windows for many games. If you are okay with games being playable and stable but missing some graphics and are willing to track down and deal with problems as wine functionality changes, stick with an nvidia card since their linux drivers are still a bit more functional than AMDs. My last card purchase I got an nvidia 460 - enough card to work well with the rest of my hardware and still be able to do dx10 and 11 if/when wine has that option and (at least in my area), a budget price card.
