Awesome dude! I have been playing since day one on a PS3 with a 55" HDTV. Looks beautiful. I have a good 7.1 surround sound system too (definitive technology speakers). The sofa shakes when dragons land or giants walk and you can tell where everything is by the sound. The game is so amazing on a big HDTV with surround.
i don't use the 7.1 as the kids are sleeping.
but yeah, 55" and a CMOY amp and some good Sennheiser HD280.
I turn the music off and now when a dragon swoops down on me I damn near [censored] myself...
