The I5 isn't as fast as the I7, and the I7 920 is the same price as the I5 comparable processor. A 500W supply is barely adequate for a medium end graphics card, for a high end you'd need at least 700W if not 1000.
Sorry, just didn't want you to end up with something you'd be disappointed with.
Mind you it comes with a lot more of course. The barebones packages are the most affordable. I imagine the I5 will do everything I need, but thank you just the same FL. By the way, how much faster will the I7 be than the I5?
Okay, maybe I don't need a high end graphics card.
