I know the 3820 is more future proof, but basically I just need a decent gaming pc, and I'm also concerned with using less power, quieter running etc. The 2700K seems to perform more quietly and power efficiently than the 3820, but from the above supplier there isn't the price difference I'd expected (yet, prices may drop, I suppose). If the 2700K was substantially cheaper then I'd definitely go for it given the excellent reviews from reviewers and owners, but the fact that both systems are similar prices and the 3820 being more "future proof" is making me hesitate.

Any advice gratefully received. Thanks.

p.s. I'd also consider a 2500K if price was right, or even ivy bridge 3770K.
btw Why, when I use edit and then click confirm, does it say "you are not allowed to edit this post?"

The biggest key between this processors come down to what you are going to be doing with them. The Intel® Core™ i7-3820 supports the quad channel memory and the board will support PCI-E 3.0 but you really can't overclock it.

The Intel Core i7-2700K is an unlocked processor that will allow you to overclock but you can't take advantage of PCI-E 3.0 with it and it is only dual channel.

Now since you state that you want to game with this system my advice is to get the Intel Core i5-2500K, good cooler and overclock it up over 4GHz and spend the extra money on an SSD and you will get better overall performance then you would wiht the other items out of a gaming system.

Thanks for the prompt reply, Christian. Very clear, sound advice. A blessing to my mind which feels rather overheated thinking about the whole thing.

Is the cooler in the proposed builds I posted what you would consider good enough?

Plus, what about the fact that from CyberPower atm the 3820 and 2700K builds are similar prices?

Finally, I read somewhere that the 2700K overclocks better (ie a higher percentage of them will successfully OC to a decent speed) because the 2500K's on sale now might not be good as the older ones (or something like that).
