The PC graphics would most likely be able to play at 1680 x 1050 and 1929 x 1080 (OR EVEN BETTER!!), which is SIGNIFICANT over console gaming.
But no split screen for PC. :(
Remember its just as easy to hook a PC to a TV as its is a console, and you can save $$ by watching HULU (over DVR), and can use the XBOX controller while relaxing on your couch. It a shame consoles are so expensive, b/c I might just get one.
