New Computer: i7-3770k or i7-2700k?

[charliechip95]

I'm building a new computer for the first time sometime next week and I'm not sure which CPU would be best. The Ivy Bridge processors released yesterday on Newegg and the performance increase (if this article is to be believed) is an average of 3.7%...

I'm not planning to overclock, at least for a good while. I would like to feel like I had the option to though, and a lot of concern has been raised over Ivy Bridge's heat dissipation. They tend to get way hotter than Sandy Bridge processors:

The Ivy Bridge processors also supports PCIe 3.0, but I don't see why that would be necessary, as the GTX680 I'm getting doesn't seem to use the extra bandwidth (and probably doesn't need to, considering the performance you get!) Correct me if I'm wrong on this.

So, for me (building a new computer for the first time, no current overclocking plans), would you suggest I get the new 3rd gen processors or stick with the already established 2nd-gen?

Here's my planned build:

If the PC is for gaming then go with SandyBridge. It overclocks better. You wont need the overclock now but later down the road. As for now the IB overclocked has been heating up too much and is a less stable OC.

You correct the 680 doesnt even come close to PCI-E 2.0, much less 3.0.

I will suggest go for i7-3820 with P9X79... the price different only around $40 - $60..for the whole system... and you can upgarde to highest Socket 2011 CPU in later

 

[charliechip95]

sonexpc: I heard LGA2011 motherboards are not as reliable as LGA1155 yet and are much more likely to brick, is that not true?

Which ever one is cheaper.
It all comes down to overclockablitly vs power efficiency.

i7-2600k. It can be overclocked for much more performance than an ivybridge chip can hit.

 

[sonexpc]

make it simple .... for $50 different even i7-3820 running on the same performance as i7-2600K or i7-3770K I still go for i7-3820.... if i7-3820 not exist .... and only available i7-3920K..... then I will stay with i7-2600K in Socket 1155...

Most review I see is i7-3820 running better than i7-2600K and is very easy overclock.....

If you really want to force the CPU to the highest Ghz ...then you may hear some people say not satble.... but use just the basic P9X79 MB for 4.2Ghz should not be any issue... ...

and you can allways upgrade to i7-3920K ( this one is really good for overclock ... but is close to $600) ...

Here is the setting someone use AsRock MB to Overclock to 4.5Ghz

I would say go with the Sandy Bridges. With the Ivy Bridges you're only getting a slight increase in performance. You're also getting better graphics but for gaming you probably won't use the integrated graphics.
