My computer is 3 years old, and it cost 700 dollars at the time. despite it's cheapness, it can do everything I need, other than current-gen gaming... I got a 300 dollar xbox for that. totaling 1000 dollars, for a computer, and a gaming system, instead of a computer that is also a gaming system.
Frankly, my monitor quality is much better than my TV (shows where I spend most of my time, I guess). The HD and wireless controller can be done, btw. It's a fairly simple install for the controller and my graphics cards do HD. As for the rest, it's probably a matter of taste. I'm happy that my PC will do more than just play games, though it does irk me a bit that there are a lot of good games out there that will not be ported to the PC. I'll probably have to break down and buy a console if that trend continues. I understand why it's happening, but it's still irksome.
