Keep in mind that a decent, midrange 6,7 or 8 series card - pretty much a 6600 GT or better (6800, 7600, 7800, 7850, etc) card will be able to run WoW at reasonable settings with max sight distance.

Plus, WoW is capped at 60 FPS (although I THINK you can override that).

So, for your non main boxes, even a cheapo PCI-E card can get you up and running:

Here is one for $43 after rebate but the reviews are not so hot. Bottom line is that for $75 bucks you can get a high quality, playable graphics card. If you really want, upgrade to 8600s, like I did. More than good enough for boxing purposes - can literally run 2 copies of WoW on a decent dual core system (with 1.5 gigs of memory or more) and will pump out 60 fps almost constantly no matter what is going on. They run about $150 - $180 depending on the type - 8600 GT or GTX.

I skipped the entire 7 series generation - going from 6 to 8. There just was not a compelling enough value to go from 6 to 7 to 8, especially given that WoW has such a low graphics requirement.

That said - the 8 series is still a bit unstable graphics wise. It does not crash for me but my 8800 GTXes still have some features missing and some oddities. For general WoW playing though, the 8 series is a good bet. Just don't get a 8200 or something aimed at the low end. Those cards have nearly crippled level of functionality.

Personally, I stay away from ATI/AMD (AMD processore are fine - their graphics cards are horrible for linux). Their open source driver support is horrible right now. nVidia is not much better but at least it is workable. ATI/AMDs is just so horrible its not worth considering in its current state.
