Introduction
The conclusion of our December 2010 $500 PC story hinted exactly where I hoped to take this month’s gaming rig. Specifically, I was interested in an AMD Phenom II X4 quad-core processor paired with Radeon HD 6850 or GeForce GTX 460 (1 GB) graphics. However, I anticipated that pulling this off would likely mean building a $600 gaming machine, a move that would throw off our clean $500/$1000/$2000 dollar brackets. So, what sacrifices would be needed to keep this build on target?

| Total Price | $527 |
Many of you enjoy quad-core computing on the cheap thanks to unlocked dormant cores on AMD’s X2 and X3 processors. But, since we’re only batting 60% on the unlocking front (with full system stability) in our System Builder Marathons, I wasn’t going to risk competing in a well-threaded application suite with anything less than four cores.
AMD has a few attractive quad-core offerings within range of this system’s budgetary constraints, and buying into one means setting aside at least $100 for an Athlon II X4 640. Fortunately, DDR3 is now super-cheap. Utilizing 4 GB, along with a familiar $60 Socket AM3 motherboard, leaves $300 for other components, paving the way for unprecedented graphics muscle at this price point without sacrificing PSU quality.
The Athlon II X4 640 is the perfect choice for assembling a true $500 Gaming PC. At the other end of the spectrum, the $145 Phenom II X4 955 Black Edition is even more appealing to enthusiasts like us who love to overclock without constraints. It offers a 3.2 GHz clock rate, an unlocked multiplier, 6 MB of shared L3 cache, and a fairly decent heatpipe-based boxed cooler.
While it's not worth sacrificing graphics muscle or bumping us all the way up to another $550 build, I was willing to break the bank and get my hands on the cheapest quad-core Phenom II with abundant L3 cache: the X4 925.

Have fun overclocking that rig!
I'd choose my O/C'd i3-530 @ 3.75 GHz (stock, air-cooled) over any of the new Sandy Bridge offerings any day.
The 2100 just cannot compete with that- it's marginally better than a first-gen i3, and it cannot be pushed harder.
*Hopes Bulldozer will be ready by that time*
++ on the PSU (finaly not a 500W+ waste)
+ on the case (looks decent)
Edit: Why Did I get a Minus one the second after my post was submitted?
There is a list, but it requires reading the story through page eight, at least =)

Numbers aside, looking forward to the next SBM.
I hope Tomshardware editors never stoop to writing reviews geared to people that won't make the effort to look up past articles.
yeah because who would want to live in a world that's convenient......
Sorry, can't read with my foot in my mouth.
I was thinking it would be more in my first post, but a quad-core SB can be had for $60 more, a mainboard can be had for $5 more, so now that I've actually looked it up, you can get into an i5 Sandy Bridge with a decent Asrock mainboard for a total of another $65. Overclocking on the stock cooler? My guess is results would be similar.
That would be a 13% increase in price, and I'd be willing to bet the overall performance difference would be more than that.
The better you know your software needs, the better you can tailor your system. I think a lot of gamers would shift as you would for the better graphics card, but that would actually hurt some games that need the stronger CPU. World of Warcraft is an example - while Cataclysm brought changes that make the video card much more important, the CPU is still a major player and when player populations get high the most critical element. It's something I think FPS multiplayer gamers might think about as well.
Thanks one-shot, but I'm not sure how else I can help you here. The complete list of comparison hardware is right there on the page called Test System Configuration And Benchmarks. You have this quarter's hardware and last quarter's hardware in successive tables. I'm not sure how much more convenient we can make it. If you have any suggestions, please suggest away!
Best,
