I want to upgrade from a geforce 6800GS card.
What is the fastest video card that will run LOMAC without driver issues ?

I tried LOMAC on an ATI 4870 but had problems with AA and texture (a white line around the plane's edge).

Thanks

Well since you got a 6800 it's most like an AGP card, which is a problem since there's virtually no more AGP cards manufactured anymore, which means you may need a new motherboard... which in turn means a new computer.

So, is it an AGP card or not? lol

It's a PCI EXPRESS card.

I'm struggling between a 9800GTX+ and 4870.
There appears to be lots of driver issues with 9800 for the flight sims.

What do you like ?

you can go here to compare any two cards: http://www.gpureview.com/
Personally I'd go with a a 4870-1gig card it doesn't cost much more than the 4870-512mb card. Just curious, what cpu are you running?
