Ever thought about plugging your PC to your TV? Get the benefits from both.
I don't have all the facilities to support it, I know it's only a couple of wires and a remove controller, but I don't feel the need that better graphic is worth relocating or adding a PC to the living room for gaming. Mod wise, since Morrowind, Oblivion, Fallout 3 and NV, I have rarely try the community mods.
I suppose I am getting aged up

Better graphic no longer means better game experience for me, what I see on the net in terms of Xbox and PS3 quality is enough for me.
I love to tell my computer chair to buck off.
