Sorry but I will have to side with Garcian Smith on the PSU debate.
I don't like OCZ either for something as important as the PSU.
Seriously the PSU is the MOST important piece of hardware for stability.
Stick with Corsair or Seasonic or even Antec if you really want to save $20 but I would just get the Corsair personally.
Don't worry your PC will be able to run any game that comes out for quite awhile since they aren't really pushing the graphics edge due to consoles. It will certainly look much better than anything the PS3 or 360 could pump out and it has all the other benefits of a full fledged PC :) If you throw mods into the mix, it means that almost every game you own will have tons of free add ons, levels, skins and other gameplay changes that extend the life of the game. Easily the biggest strength of PC gaming in my opinion and I own all consoles and enjoy them for the games they do well (fighters, hack n slash, racers, flying games)
