Best LGA 1150-1156 CPU?

Solution
1155: 2500K (no HT), 2700K (HT). Good price on the used market, very easy to overclock with a cheap air
cooler like a used TRUE. 5GHz every time with a 2700K and a Venomous-X. Built three so far with an ASUS
M4E board.

1156: i5 760 (no HT), i7 870 (HT). Also well priced on the used market, easy to oc; low latency P55 means
performance is good, and the PCIe is not as limiting as many assume.

1150: can't comment, no personal experience yet, but plenty of info on the forums. Personally I think
they're a waste of time. If I want the CPU performance I'd just get a 2700K. If I want PCIe bw then
I'd go X79 and a 3930K C2. Z87 doesn't offer both, so no thanks. Only thing lacking in the older chipsets
is oodles of native Intel SATA3 ports, but...

like Stacks said...it really depends on what you are going to do. for gaming i have a i7-3770k, but an 15 would have been just as good because games don't use hyper-threading much yet. for work i use a i7-3930 (LGA 2011) based system. but i do a lot of CAD where the 6 core might come in handy

the speedup over SB is pretty lame (hence the title of the toms review).

Plenty of data you can browse on my site btw:

Wow, I'll go with the 2700k. How did you manage to get 5ghz out of that?

Easy with any good mbd. As mentioned, I use the ASUS Maximus IV Extreme. Bought several so far,
all used, costs varied from 87 to 150 UKP, all boxed with original accessories. Here are my BIOS settings
and CPU-Z (my main setup is an open-air config, ie. not in a case, which I use for parts testing, general
benchmarking, etc.):

That's with max 32GB RAM @ 2133MHz and three GTX 580 3GB cards. After that I obtained
another M4E, fitted it with just 8GB RAM and a temp GTX 460:

It was later changed to 32GB @ 2133, Quadro 4000, SSD, etc., which I sold to an engineering
company for use with ProE, Magics and other CAD apps.

The 3rd setup has a temporary Pentium G840 atm while I try out a 2700K on an EVGA Z68 FTW.

The Venomous-X units were about 20 UKP used, though I did replace the stock fans with
two Coolermaster Bladermaster 12cm PWM. The 2nd system with the Quadro 4000
had its VenX changed later for a Corsair H80 to make the company's transport issues
easier to handle (less chance of damage in transit) which also dropped the temps a
little aswell.

Btw, I was surprised to find the M4E fits just fine in an Antec 300. :D


Anyway, any good P67 or Z68 board should work fine. Personally I prefer ASUS, their ROG
series have good BIOS setups, especially with respect to being able to get max RAM working
at a nice speed (my ASUS P9X79 WS with a 3930K C2 has 64GB @ 2133 and four GTX 580 3GB).

Wow thanks, you've been a big help
