Build or Buy?

I highly recommend building this on your own.

In terms of the CPU I would just go with the 4670K. It has the added benefit of being able to overclock in the future. You can have decent gains depending on the game when overclocking. PS2 is one such game. Performance in PS2 will still be good without overclocking, but itdoes certainly help. Don't expect it to double your FPS though.

That 7870 you are looking isn't nearly as fast as a 760, and the 770 blows it out of the water. Not exactly sure what you were looking at to think that. If you wanted a Radeon to match a 770 you would need a 7970 or 280X.

For the hard drive I have been using 1TB for years now and never ran into space issues. Though I am not storing any kind of media (no HD porn) or say a butt load of music.

I personally would go for a better case if you want one. You will be looking at for years to come, so splurge on it. I only chose that one to help keep the budget down.
