Aka me.

Or want quad channel memory. Granted "quad channel" is not something that you notice in performance in everyday use, however, you can install MOAR RAM that way smile.gif

If it was unlocked, it would fill the gap between the 2600K and the 3930K nicely, its much more attractive than the 2700K. But most people don't need quad channel memory or PCIe 3.0 yet, and without being unlocked, it feels like it's only purpose to lower the entry point for 2011.

It might be a good workstation CPU though. Plenty of power and a nice set of features without the instability/hassle of overclocking. And then you have the option of upgrading to a 3930K/3960X without building an entirely new system.

4.7-4.8 have been achieved on air on the 3820 C1. The reviewers chips are mainly C1 from what they have found. The 3820 does pull ahead of the 2600k in several reviews. Sometimes it minor, sometimes major. The only time the 2600k pulled ahead is when memory latency was important. The 2011 socket and its quad channel memory was slower. One reviewer took the quad out, and just done a dual channel test and it then picked up the scores significantly.

Did anyone forgot Z68 only offers 16 PCI-e 2 lanes as opposed to 40 PCI-e 3 lanes on X79? Not to mention support up to 128GB of memory (RAMdisk anyone?) as well as BLCK overclocking. And you can upgrade to six and eight core CPUs in the future as opposed to being locked to quad on Z68.

X79 is easily superior but it's up to each individual to decide whether or not it is worth the higher price tag.

Unlike the Z68 you don't need an unlocked CPU for X79. With BLCK straps you can overclock any "locked" CPUs perfectly fine.

That makes no sense, if you say, have dual HD7950 or dual Hd7970, that saturates the dual 8x slots on a Z68 board...If I was purely gaming, I'd rather spend more on the parts that matter (GPU) than parts that don't really matter, no matter what reviews say (CPUs, bar a few RTS') and thus a budget CPU, as long as it could drive the cards I had, would be a good purchase. Even if I could afford a 3930K, if I didn't use the extra two cores...Spend the difference on a 240GB SSD and enjoy faster load times, it's a larger difference in games than between this and the 3930K in gaming.

That is epically whack. I have a RIVF an two 7970s sitting in the closet waiting for this CPU.

Good solution for you are looking at X79 just for the quad channel and PCIe 3.0. Would like to know more about overclocking.

X79 has BCLK "straps" 100MHz, 125MHZ, 166MHz, and 250MHz.  The 3820 has a multi of 43x max so you can OC using different combos of BCLK straps and multi.

Most board won't do 250MHz AND early benchmark said it was topping at 4.8-4.9 GHz
