I want to bring a 3D TV...

Well I bought my PS3 about 11 months ago.

anyway, I just started to play batman, uncharted 3 and gran turismo 5 and I read that it compatible to 3D and I play with my PS3 on my 37' hisense and my 19' philips (if my brother want to use the large screen) and I thought if i bought sony 3d display it will be good for me.

here is the question: do I buy it or not? and the 3D games worth to be played 3D or i play it 2D? finally if you want to recommend me any display, I will appreciate that. thank you.
