The general principle of Windows games always running better in Windows than with Wine in Linux is true. This is largely due to video driver limitations and issues, but Wine itself simply isn't perfect at handling directx. That said, it's not terrible.
I currently use Lubuntu 13.04 64bit on my desktop with an Nvidia GTS450 and their proprietary drivers. It runs old games like Decent FreeSpace and Tribes perfectly. Using Playonlinux, a frontend for Wine, also makes it easy to install games (and Wine itself actually). However, I have not tried any other games with 13.04.
Years ago I played Star Wars Galaxies and World of Warcraft in Slackware Linux using Wine. SWG ran pretty much the same in Linux as it did in Windows, but WoW was noticeably slower and had a few graphical glitches. With this experience, I would imagine that the Sims games will function acceptably using Wine, provided they function at all. Quake actually has an open source native Linux client called Open Arena, which I believe is based on the Quake 2 source. It runs great and has bots you can play against offline. Doom 3 and Quake 4 should be playable with Wine.
The bottom line though is, it's easier and more effective to just dual boot Win7 and Linux. I do almost everything in Linux, but I play pretty much all my Windows games in Windows.
