I played World of Warcraft during months (Wrath of the Lich King to Cataclysm) with Wine running on Debian with a NVidia card. It was not faster nor slower than Windows (some tenths of FPS, depending on zones) and it feels more stable. They have a compatibility database with fixes or workarounds for some games, and although they have their share of incompatible games the list is smaller every day.
At times, WINE is better than Windows... mostly because there are games that you can not run with recent versions of Windows and WINE can.

Sure? NVidia has propietary drivers, but their performance is very good. It is true that their drivers are propietary (there are some free drivers, but the performance and capabilities are sub-par) but most distributions have their easy installation methods for them (I got Debian and only needed apt-get install nvidia-drivers to get the thing working). In worst cases, you can download a driver installer from NVidia and you'll need to update it manually (every time you update your kernel and every time you want to get another version) but that's all. Even when Debian had not "official" drivers, I was able to install those drivers without problems.
AMD/ATI, on the other hand, have free drivers... but their performance (at least a few years ago) was not as good as NVidia. I don't really know how good is ATI on Linux at this time, but I've heard (so don't believe on this) that latest cards need some kind of propietary drivers to work at full performance.
And Intel... well they had free drivers (I don't know if they still colaborate with Linux community) but Intel graphics performance is minimal. Note that this is not a Linux problem... Intel never had a gaming video card.
So (until someone tells me that ATI have fixed their issues with Linux), I'd say that NVidia is the way to run games on Linux or WINE.

Sometimes going all the way is just a start...
