MTW and Current nVidia Cards

[Redav]

So... as an 8600GTS owner in an old XP machine, I'm well aware that battles are unplayable. This hasn't bothered me too much as I was happy to play at the strategic level however recently I thought I'd like to get back into fighting the battles. I'll try this alleged 'possible fix' tonight but I'm not holding my breath - I never get this lucky.

I'm going to get a new machine early next year and I was wondering if there's still this issue with the current nVidia cards (or even ati?) under Windows 7 or was it limited to 8xxx and 9xxx cards and is now a thing of the past? If it's still an issue, I was going to find an earlier card to play (there's also compatability issues with Star Wars X-Wing so I was doing this anyway) so I was wondering if there is a recommended card to find? Originally I had a 5750 and it was obviously fine but I upgraded it to the 8600 so MTW2 would be playable (it's ironic that I shot myself in the foot) and I no longer have this card. I had imagined a high end 7xxx series or should I go for a 6xxx or even an ati? Any suggestions?

Thanks in advance.
