I need advice on desktop PC to purchase?

The situation is pretty dire. My laptop hard drive is failing and I need to get a new computer, a desktop this time, pretty soon. My budget is <$1000. I really don't have time to research the differences and find the best deal or best machine, so I was hoping some of you could help me out. I need something that can hold 2 hard drives. I occasionally (more like sporadically at this point) game: Bioshock Infinite being the most stressful on my machine. I occasionally watch movies on my PC too. I LIKE (emphasizing that) AMD processors, but would be willing to switch to i5 (or i7?) if someone can convince me I need the horsepower or would be better off with it. I don't need a flashy graphics card, just something good that will work with what I've mentioned above. I like fast boots too!

There are so many good looking machines that I can't seem to find anything that DOESN'T sound great. So I need help sorting through the infinite number of machines: Lenovo, HP, Toshiba, Dell, etc. Etc.

I would recommend building your own. You could build a very good pc for $1000
