Aren't you going to post the 'downside' to that? I.e. it costs a fortune to get a PC anywhere near good enough to play modern games on.
Here in the US it doesn't cost a lot to buy a puter that plays modern games though. Less than a PS3 at launch.
My computer can play all the latest games and would cost about $300 to replace with a faster puter, So long as I go with the local stores weekly specials on a good week. Not including mouse, keyboard, PSU, case and monitor.
