Total Utilization Analysis
Since our 20 games are very different when it comes to CPU/GPU utilization and dependency, we have to be very cautious when drawing any conclusions. No single answer can be applied to all games.
Take Alien vs. Predator as an example. You can easily play it with a weak CPU and a strong graphics card. But using Grand Theft Auto 4 EFLC with a setup like that would severely limit frame rates, since it's so CPU-heavy. And while budget hardware can hit more than 60 FPS in old games without breaking a sweat, the DirectX 11-class Metro 2033 and S.T.A.L.K.E.R. titles are unplayable without a good graphics card.
There are a few things you can take away from these graphs. Even if a single-core CPU is only 88% utilized, you are still missing out on about 30% of your potential graphics card performance. With a dual-core CPU, the untapped potential is just 9%, and a quad-core CPU can bring this number down to around 5%. It's important to note that multi-core CPUs decrease the jerky gameplay you might suffer on a single-core system when games need to load new resources. In any case, all four cores are very rarely fully used, leaving software with some breathing room.
In this overview, all results from the different benchmarks are added up without weighting. All values are in frames per second. We decided to not convert them to percentages, since the results tend to point towards dual-core CPUs, although most new purchases will likely be CPUs with at least three or four cores. As you can see, the performance gains from overclocking the CPU are almost non-existent at these high graphic quality settings, the 1920x1200 resolution, and with a GeForce GTX 460.

It's disappointing to see that devs still aren't taking advantage of multiple cores like they could.
Would there be any performance difference between windows 7 32bit and 64bit?
Assuming you use the same amount of RAM [4GB].
Great run down guys. I would of liked to see a three core benchmark thrown in there, but what can you expect from a dual core with HT.
@KingArcher Unless the program was designed for x64, you had more than 4GB of unused RAM that the game could use and could use more than 4GB I highly doubt whether or not your on x86 or x64 would matter.
@nativeson8803 What difference would it make on games that are still GPU limited at two cores? Even then, there were games limited by the GPU at four cores. Taking advantage of a CPU with four cores or more is going to be hard when you need more GPU to get more frame rates.
@Slayvus almost true. The difference would be @2 GB of available memory. NT x86 kernel only allows an application to access 2GB of address space with the other 2GB reserved for kernel use. In NT x86 world each application can only access 2GB of memory, with the application getting rather unstable once it goes over 1.8 GB. This limitation also applies to the NT x64 kernel running a 32-bit problem through WOW64. Its something left over from the NT 4.0 / 5.0 world.
Just keep in mind that these result are relevant in the context of using the GTX 460 768 MB, which is the real bottleneck here. Better GPUs and/or multi GPU setups would shift the bottleneck towards the CPU.
In the end, it's all about finding the perfect balance in hardware. If you want my advice, pair the GTX 460 768 MB with a fast dual core, but get a good quad with higher end model GPUs.
This methodology should be used to new cpu/gpus/games reviews.
I'd like to see them test the first Supreme Commander.
It still taxes the most powerful systems
They should have used Phenom II X6 and test with 1/2/3/4/6 cores enabled. This made me want more of this because there aren't any 6-core benchmarks.
Make a Part 3.
+1 deisu

I totally agree with archange. I understand that you're trying to go for the "norm", but if you're looking for bottlenecks, you need to remove said bottlenecks to see where it truly lays. Start with a quad core clocked at ~3.5ghz and swap out gfx from there. Push and push to see where it truly lays instead of going for a baseline. Although you can use that baseline to see what the "average" person might use. If the article is truly about the bottleneck, use something beefier than the 460.

And overclock the crap out of the 1055, 1075, 1090/whatever you use.

Was thinking the same thing
Lets see GTA4 with a dual-socket 6-core CPU in SLI with dual GTX 280s
EDIT: 480s
Yes, but for such a setup, TH should first get one of those compact, autonomous Nuclear Reactors... And a lifetime supply of depleted Uranium. xD
in BFBC2 i doubled my frames going from E8400 to Q9550 with a HD4870 1gig crossifre setup
"Mass Effect 2 needs at least four cores."
"With this game, you should grab a quad-core chip [...]"
With 63.7 fps on a single core there's absolutely ZERO reason to buy anything more expensive for this game.

THEN WHY THE HELL DID THEY NOT USE A 480 GTX 4way sli to rule out gpu bottlenecks ?
Again, this is a bad test. You're testing for CPU usage...using max graphical settings. As such, you're seeing the result of a GPU bottlenecking teh system.
Set everything to low, THEN test the CPU. This type of test reveals nothing except that the GPU is more often then not the primary limiting factor in gaming.
I like the fact that power usage at the wall never cracked 300W. That tells me my SG-650 should be adequate essentially forever.
The points I take from this are:
1. Any [new] GPU bought for serious gaming at high resolutions should have 1GB.
2. As a requirement for gaming performance, overclocking is unnecessary. This means that massive coolers and lots of noisy fans are also unnecessary.
3. Data loading issues that show the benefit of additional cores would undoubtedly show a benefit from a SSD, e.g. less stuttering.
4. A hugely expensive edong is not required to get decent performance in most games.
It would be a lot of extra work and involve arbitrary choices, but it would be interesting to see the effects of reducing settings, even a little. At high resolutions, I'm not sure my eyes are even good enough to notice whether or not AA is on. How much does a reduction in settings shift the bottleneck off the GPU?
