I was originally going to 'build' you a PC, but I was pretty impressed by the specs and price on that one.
Case: The Antec series of gaming cases are easily the best around, I might have recommended a 600 or 900, but 300 is more than enough, especially when it's built by people who know what they're doing.
Power Supply: OCZ is a good brand, 600w is pretty much the perfect amount for what you need.
CPU: The great thing about this processor is that not only is it a top notch processor, but the potential capability for overclocking is outstanding. I'd rank this PC as one of the top quad cores out there, matched only by similar i7's (which are typically 5 times more expensive).
Motherboard: A Gigabyte motherboard is the way to go most of the time, and the 760g is good enough quality to guarantee it won't bottleneck your system. Additionally, you'll have excellent hard drive speeds and USB 3.0 support with this motherboard.
RAM: Corsair is awesome, DDR3 is awesome, and the speed is some of the best you can get with the AM3 core.
Hard Drive: Solid states are still way too expensive. Seagate has gone downhill a little as of late, but it's really not that big of an issue. You could always use your old hard drive, but I really don't see it being necessary. The 500gb will ensure you won't run out of space in the foreseeable future
Graphics Card: Sapphire is hands down the best manufacturer of ATI cards, and the HD 5850 is hands down one of the best graphics cards on the market today. It outperforms most of nVidia's GTX series and is still considered top of the line as far as ATI is concerned. There isn't a card I would have recommended otherwise, and this way you're probably getting it cheaper than you would otherwise.
Sound: Not a big deal but 7.1 will give you anything you wanted as far as sound is concerned, no need for anything more.
Optical Drive: No need for Blu-Ray, that's a huge waste of a lot of money. 22x DVD is a little above the standard anyway.
Couple all that with Windows 7 64 bit and you've got what I would consider an upper-range gaming PC. Those specs are about the best you can get without being a stupid enthusiast who wastes a thousand pounds on Crossfire or SSD.
Anyone recommend?
