What video card do you recommend?

[Lord_Jeremy]

Hey. I'm looking to get a decent video card to replace the GeForce 8800 GT that I borrowed from a friend. I'm looking at either a GeForce 9800 GTX+, a GTX260, or maybe even a GTX280. Can anyone tell me if these cards are sufficiently compatible?

If the above cards have problems, it'd be nice to get a list of cards (preferably NVIDIA) that are known to work well with Leopard on a PC. I'd like to get as high-end a card as possible, since I plan to dual-boot windows for gaming purposes.
