PC-Gaming on a 3D TV?

[Cr1chton]

I was thinking of getting a passive 3D TV, and I realized that 3D gaming is a thing. Furthermore, in my Nvidia Control Panel I have the option for stereoscopic 3D.
My question is, however, whether it impacts performance any more than just running a game in 1080p.
Another thing I am uncertain of, is whether a special kind of TV needed for gaming; as in, other than passive 3D.

I know it splits fps and resolution in two, so I am only going to play games that I am certain my system could run at 1080p, 60fps. Really looking forward to the old Crysis(-es) and Batman: Arkham Asylum/City.
Prior to getting my hopes up though, I thought it a good idea to get some information from more advanced gamers.

My rig is:

Core 2 Duo E7300 2.67 GHz
4GB RAM
Nvidia Geforce GTS 250 1 GB GDDR3
OS: Windows 7 64-bit
