Before we wrap this up, let’s consider the aggregate performance data. Keep in mind that we removed the Skyrim results from the following chart because the game's patch altered performance too significantly, rendering a comparison completely invalid.

First up is application performance. On average, the Core i5-2400 does quite well against AMD's FX-6100, especially in light of its motherboard, which artificially hamstrung it with a single memory channel and an inability to specify a constant 3.8 GHz. We did see a couple of benchmark situations where the FX-6100 took a first-place finish when it was overclocked to 4.5 GHz, due to its high clock rate, dual-channel memory, hexa-core architecture, or a combination of the three. In general, though, the Core i5-2400 comes out on top.
As far as game performance goes, the new build's Radeon HD 7970 performs admirably up to the charted resolution of 1920x1080. If we were to focus more intently on 2560x1600, though, the benchmarks suggested to us that the two Radeon HD 6950s in CrossFire would have fared much better.
It’s a real shame that ASRock's P67 Pro3 SE isn't equipped with better BIOS overclocking options, and especially unfortunate that it was unable to run our memory kit in dual-channel mode. We’re not sure how much of an impact this had on the final results, but it's possible that we'll try a Core i5-2400 on a different motherboard next time around just to compare the two platforms.
Regardless, looking at the average performance and power consumption of this quarter's build, a Core i5-2400 and Radeon HD 7970 combo are a better bet than an overclocked FX-6100 with two Radeon HD 6950s. Despite its well-documented flaws, the new build is a powerful little system more deserving of our $1250 budget.
We're especially looking forward to Day 4 of our System Builder Marathon, where Thomas will compare the overall value of our three systems. Not to give too much away, but our top-end machine also centers on Radeon HD 7970, so it'll be interesting to see how much platform alacrity impacts gaming performance.

I like how the 2400 is used but would it be okay dropping the cooler?
Read only optical drive? This makes no sense and is probably the worst skimp Ive ever seen. Spend the 5 bucks for a burner. Iso image anyone? This is an enthusiast level build... no mud flaps, no sale.
I desperately want a monitor at that resolution.
For the price, the lack of a larger SSD seems like an oversight. I would think anyone really considering this build would have done better to get a larger SSD and a 7950 or 7870. Or perhaps a single large hybrid HD would be a better option.
When you compare their overclocking potentials, they have about the same performance. And then there is the availability of the GTX 680, which is not. So it makes since why the 7970 was chosen.
The 7970 has better compute potential too. But I don't think that is relevant for a gaming box.
My thoughts exactly. This story was probably done before Kepler, but now with the 680 launched, the editor sure must be feeling a bit shortchanged.
Of course, the fact that the 680 has disappeared off the shelves is a different story entirely. In any case, within the next few weeks, we should see significant price cuts on the 7970, potentially making this build relevant once again.

Seriously folks, the NZXT GAMMA Classic Case is the best ATX case for under $50.
Also I agree, 64GB SSD is tiny for gamers. Its fine in an office enviroment, where you only have just the production programs that you use on a daily basis installed, with the actual data stored on a server/database. But for gamers whose Steam folder alone is in the 100s of GBs, its pointless.
Also, why bother with an aftermarket heatsink if you don't plan to overclock? I can understand if your after a low/noiseless pc (like me), but considering your running a 7970 and noisy stock case fan, it's a waste of money.
On a positive note, the $650 build was OK.
Not all of us need to run our games off an SSD. I use a 64GB SSD to boot from, and use my 7200rpm HDD to run my games, and it works just fine. I think people are being a little too picky. Especially about a build that will eventually be given away for free.
i think you meant 2560x1600!
Also interesting to note that the FX-6100 seemed to perform better in this comparison, then against the i5-2400 configuration used in the $600 December SBM which wiped the floor with it.
I understand that SSD is a no-brainer for a well rounded system. Heck, I myself would never spend north of a grand on a pc and not throw in an SSD. But the FPS per dollar is hurt by adding such an expensive storage subsystem.
Im pretty sure they stated in the $650 build that they had this stuff picked out a couple months ago, so pretty much just as the AMD 7xxx series came out, long before the Nvidia 6xx series was released. They also stated they are sick and tired of using the 2500k in their builds. I like it when they experiment. Otherwise we wouldnt have seen how horribly bad the bulldozer build was last time.

That was in the previous SBM so you really haven't been looking very long. I gave you a thumbs down just to cancel out some of those thumbs up you received
