I might be in the market for an nVidia 7800GT 256 MB PCI-express graphics card soon.

Anybody have experience with these? What's a good brand? What to avoid?

Prefer SLI capable as will probably add a 2nd card at a later date.

It will be used for World of Warcraft on an A64-3500.

Not sure that the extra $$s for the GTX is worth it considering the rate of "new" cards coming out. Also the GTXs will need a new power supply as the current one is an Antec 480W.

I remember, only a few months ago, when the ATI X800 Pro was top of the line. Now its an also-ran.
