Get a HTPC instaid after selling your rig... Nothing too fancy just one of those llano chips
Really depends what your looking for in games.
First off the only games people play online on xbox is CoD forza some BFBC2 and BF1943 and the new releases of the week, (after a month no one will play the new releases) Half of the reason is because you need to pay Â£40 a year for there online service
Secondly the Xbox has like 10 RPGs that are any good.... Actually not even that and the libary of games consists of Shooter shooter shooter
On the PS3 it has GOOD RPGS
and a large list of them (and one of the reasons i brought one anyway)
People play cod, MAG borderlands RDR GT5 LBP2 resistance and loads of other games, Part of the reason is because ONLINE IS FREE!
Also i love the media functions of the console and wants me to watch BLU RAYS!
