i game on a 32" Samsung TV 1080p Full HD. and i am loving every moment of it.
i suggest you do the same. 32" is the perfect size for me.
also got PS3 hooked to the same TV and switch between them whenever.
if u want to do that get a 3D Samsung TV 32" for about 3grands (not sure). i can guide you on how to play almost all games in 3D. u will need to get nVidia 3D vision for better 3D.
i just downloaded Dishonored but haven't played it yet. cant f*kin wait.
