[xXI GaMe IXx]

So just recently the wife and I started clashing about the Tv since we only have 1 a (Samsung Ln52a650 Toc). I like playing games and watching blu ray's she likes Gilmore girls. So today she asked me what I wanted for father's day I told her a new Tv and surprisingly she said ok.

So now I'm excited but don't know if I should get into 3d now and buy a 3d tv and take the old T.v to the bedroom. I know shes going to put a $2000.00 limit.Then I'm thinking maybe I should get a 40inch 3d T.v for my room.My brother thinks I should get a new 55-60inch lcd T.v for the living room (hes really Anti 3d.I just don't know what route to go since I know I won't be able to buy another T.v for a long time son can you guys give me some suggestions.
