i7-3770K vs. Xeon E3-1270v2

Thread Starter 
I'm building a computer for 3D graphics stuff. I plan to use 32GB of RAM, and am unsure whether the ECC capabilities of the E3 make it worth getting over the i7. ECC RAM is more expensive from what I've seen, and I'll have to get a motherboard to support it as well.

Does the stability afforded by ECC make it worth getting the E3?

Thanks in advance.

I'd just go for the 3770K to be honest.

Yes. Why not. But only if you don't overclock I would recommend 1230V2 or 1240V2, 1270V2 is too overpriced, just for little difference in frequency.

Motherboards are expensive (ASUS C216, ~300$), and RAM is slower (1600MHz, higher latencys than non registered ram).

32GB (4x8GB) DDR3-1600 ECC DRAM is ~280$

http://www.google.com/products/catalog?hl=en&safe=off&biw=1280&bih=831&q=8gb+ecc+DDR3-1600&bav=on.2,or.r_gc.r_pw.r_qf.&um=1&ie=UTF-8&tbm=shop&cid=1216966684016884141&sa=X&ei=VYchULvnN4bBtAa6v4DABg&ved=0CIEBEPMCMAA

And there is also 3930K (=>4.500+MHz) option.

Well, the speed drop for ECC is pretty negligible, only about 2% from what I read, but I don't have any desire to pay the extra for a server motherboard or ECC RAM.

Therefore, I suppose the question would be better phrased as, how necessary is ECC for stability?

Just get good non ECC RAM with the i7 and you will be fine, I have systems that run 24/7 some OCed and they are rock solid.

I say if you build a new system and don't OC the biggest factor for stability is going to be the drivers and software you install on it.

Okay, thanks. What do you recommend?

If you go with X79 - LGA 2011, you could get a board with 8 RAM slots and a 6 core 12 thread i7 CPU
or you can go with a Z77 board with 4 RAM slots and the 4 core 8 thread CPU.

As for the RAM itself I really don't have a favorite brand.
If you see a kit with good speed, decent timings, and good reviews for a good price... get it. tongue.gif

Much though I would like to have a 6 core CPU, and although it would be better for the 3D applications that this computer will be used for, my budget directs me to get the 3770k. frown.gif

This is my first time building a computer, so I must ask, do you have any recommendations for Z77 boards? Also, what exactly does one look for when buying one?

Thanks.
