Please leave your feedback here.

I'm an AMD fan, but if I had to choose between the 2600k and the 3820 I'd go with the latter, because it's bigger.

What's bigger the CPU ID number or the system build price?

If I was going to spend extra money on the LGA2011 platform, I wouldn't go below a 6 core CPU.

I'd rather go with a 2600k (and I did) because of how easy it is to overclock. Just hit 5ghz on 1.425v full load and couldn't be happier.

Regarding the Gaming Performance section, testing those games for a CPU review makes no sense.

You should be testing CPU-limited games such as GTAIV or ArmA2 or at least drop those resolutions at the lowest setting and use the lowest graphical details to remove the GPU out of the equation.

As it stands, the gaming performance page doesn't say anything to me.

About the CPU itself, I'd pick the 2600K instead.
Typo on last page: "the slightly slower i7-2500K" should read "the slightly slower i5-2500K"

We don't bother with non-realistic gaming settings anymore for these high-end CPU articles. Now we test closer to settings gamers are actually going to use and having said that at 1680x1050 the frame rates were still well over 60fps anyway. The gaming results only say what they need to, the processor makes bugger all difference, at least when comparing one high performance CPU to the next.

Also the games you mentioned are not “CPU-limited”, they are more CPU dependent than most games, that is not to say the CPU will be the bottleneck when using a high-end graphics card. Also you will find the The Witcher 2: Assassins of Kings to be just as CPU dependent as any other game out there...

Crysis 2 isn't bad either...

Nice review.
Just a heads up that on your Fritz Chess 13 graph it says (Lower is better) but I think it's meant to say higher?

For me i'm most concerned with the gaming performance section, and as i'm still running an i7-920, I dont feel the need to upgrade yet. Still it's interesting to see what intel are coming out with in the buget range. These chips are pretty powerful but also a hell of a lot more energy efficient that previous generations.

Is it just me or does the tick (or tock, not sure which one this is) of Intel's tick/tock release schedule seem to be becoming less and less of an actual advancement?

For consumer products maybe, but enterprise equipment will prob get the most benefit from it.

The reviewer says this new chip does OK and applications compared to a i7 920 but not in games? The 2600K barely outperforms the 920 (if at all) when talking games and this CPU isn't any different, so the 2600K must have been disappointing to this reviewer as well considering his logic.

With ACTA there is no reason to upgrade PC anymore.

At that price range it's just another slap in the face to AMD after the bulldozer failure, I would love to see all these CPU's benched in Windows 8 though, since it handles more the 4 cores and SMT better then Windows 7, I think you would see the SB-E chips rise to there price tag, and the AMD chips actually start competing.

I actually agree with this methodology of testing only in real world scenarios. I mean come on, who in the world will actually buy this type of CPU to game at 800x600 resolution?

That really depends on what games are being tested, and if the system is GPU limited at the testing resolution/game IQ

I'm holding out for an 8-core with HT ~3 Ghz processor before upgrading from my i7 920.
Thankfully, it's not like the i7 920 with 12 Gb RAM is struggling or anything, so that helps me wait.

So you first say they aren't CPU-limited and then that they are more dependent of the CPU than most games.... doesn't that make them CPU-limited compared to other games?
Sure, you still need a decent GPU to run them, but it will matter less, just how it matters less what kind of quad-core CPU you need to run a modern game (as this review clearly showed).

And I don't even see how the links you posted matter in regards to this review as that review had a GTX590, and when using more than one GPU (since the 590 is pretty much a 570 in SLI) CPU overhead can increase quite a bit when all GPU cores are at full load.

I agree with it as well, but when the results show a difference of maximum 20% between first place and last for 13 CPUs there's just not much to talk about.
Also, GTAIV and ArmA 2 are actual games, so those qualify as real world scenarios in my book.
Skyrim with uGridsToLoad set to a high level can be pretty taxing on the CPU as well.

If you posted just to insult, then you would have better not posted at all since I don't see anything constructive in your comment.

Only thing I was saying is that there's just not much to look at that page since ALL CPUs offer more than 60 FPS, except in C2, but then again no CPU offers 60 FPS in that game.
As such any extra performance doesn't net you anything tangible.

I'm very confused whether or not to buy a system based on the i7-3820 or wait until the Ivy Bridge processors come out. Which one will be faster and have more hardware support?

As I was saying no not at all. If you were using an Athlon II with a high-end GPU then yes certain games could be considered CPU limited. If you are using something like the Core i7-3820 or 2600K then no not so much

So when the real world results are not exciting in future we should look for ways to make them exciting by using settings no gamer is ever going to use?

Are you kidding? Wait for Ivy Bridge. It'll be faster, cooler, and have ~4x the graphics performance. With Virtu on the Z68 boards the CPU's GPU is utilized so the graphics card doesnt have to spool up and increase power/temps. Of course once a higher load is demand then what the CPU's GPU can handle the graphics card takes it from there.
