Want to get one for my new TV, which system has better graphics?

From what I understand, ps3 has 1080p, but 360 has the more advanced GPU?

Which do you prefer? In high school I had the ps2 and the original xbox, and it seemed back then most "serious gamers" praised the play station 2 and didn't like the xbox. I always wondered why, because xbox seemed better to me, (except no final fantasy) but I enjoyed them both.

Now it seems like most the games I want to play, like Skyrim, come out for both systems so that's not really a issue anymore.

Really, I am a PC gamer, because I love being able to mod stuff, but I just want to chill on the couch and enjoy epic graphics
