Ok, here's an AMD option:
AMD FX-8350 4.0GHz 8-Core Processor: $179.99 @ Amazon
-Picking a CPU in this type of budget is pretty straight forward. At the price, the 8350 is as good as it gets in my oppinion, but you aren't making a bad choice if you are going Intel either. If you absolutely still can't make up your mind, think if it this way: The 8350 is better with newer apps and games in general, due to its 8 weaker threads as opposed to Intel's 4 stronger threads.
Gigabyte GA-970A-UD3 ATX AM3+ Motherboard $109.97 @ Outlet PC
-A no-brainer really, the UD3 is a tried-and-true board, with great options and power delivery.
G.Skill Ripjaws X Series 8GB (2 x 4GB) DDR3-1600 Memory $59.98 @ NCIX
-Ripjaws X are pretty popular on OCN, you can't really go wrong here. 8GB is plenty for most any user or gamer.
Samsung 840 Series 120GB 2.5" Solid State Disk $92.99 @ NCIX
-A great SSD. You don't need to pay a bunch extra for the Pro, since that really just adds write-speed, which is reletively unimportant for most home use. It's write-speed you want, which the 840 provides.
Western Digital Caviar Green 3TB 3.5" 5400RPM Internal Hard Drive $114.99 @ Microcenter
-A big drive for all your other stuff. Not incredibly fast, but you don't really need speed, you need space, this does that.
Rosewill Capstone 550W 80 PLUS Gold Certified ATX12V / EPS12V Power Supply $79.99 @ Newegg
-80 PLUS Gold is always nice, and helps ensure quality components. Rosewill PSUs are built by Superflower, a reputable maker. Basically, It's a great price, while not sacrificing quality (which you never want to do with PSUs.)
Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler $29.99 @ Microcenter
-A great cooler for anything from stock to moderate-high overclocking
That puts you at around $670. This gives you wiggle room to pick out a case, (which is really purely subjective anyway) and change out other parts if you wish, like a bigger SSD.
