"CPUBoss recommends the Intel Core i7 6700K based on its performance and single-core performance." and CPUBoss shows: All core performance: Core i7 6700K: 5.8 Core i7 3770K: 7.2 Single core performance: Core i7 6700K: 8.0 Core i7 3770K: 8.4 Can someone pls explain me why lower performance cpu is recommended?

my 980 plays triple screen at 60fps on med gfx setting about to upgrade to a 1080 you wont need sli. 1080 sli would be for triple 4k screens

I want to use three monitors at 1080p bro

Gavin (04:39 PM, June 29, 2016)

Why on earth do you need to SLI 1080s? Are you trying to game at 120fps in 4K??

IDewagede Budi Dharma Prabhawa (12:59 PM, June 26, 2016)

what about 1080 SLI? its no need to upgrade? i have 3770k and i want upgrade to 1080 SLI

same here , i still have 3770k

Bodark (03:44 AM, May 18, 2016)

Came here to make comparison with my 3770k. Clearly, not much different. Plan to upgrade my rig or buy new one with the new upcoming GTX 1080/1070. But, I changed my mind. GTX 1080/1070 will fit with my 3770k without problem. No need for CPU upgrade.

I also have 3770K for more than 3 years now, I wanted to see what has changed since 2012 and it seems there is no competation in desktop CPU products. Intel makes max %10 improvement for i7 processors in every new serie and most of it because of the rised clock speed. If you are a PC games, it does not even get you more than 1-2 fps. Considering you are using "K" series processor, you can just gain that overclock with no efford. I think I will wait till they produce something which makes difference...

I have used the 3770k i7 since 2012 when I built my PC. I came to compare the new 6700k to see if it was a good time to upgrade my gaming rig. Clearly the 6700K is not that much more better of a CPU to make me go out and build a new rig. Yes it is faster but only slightly, and for being three years newer, it is clear since Intel has ZERO competition improvements in CPU speeds and performance are almost at a crawl. Also I paid $300 even for my 3770k back in 2012. Here is my rig and honestly it still holds up to most games well. Windows 10 Pro Intel i7-3770k 3.5Ghz. ASUS p8z77-V pro motherboard Corsair Vengeance RAM 12GB @1600mhz Samsung 1TB solid state hard drive eVga 980 GTX 4gb Graphics card (just upgraded to that in December. Got it for $250 over a one day Christmas sale. previously had a 660 GTX). Antec 600w power supply Dell Ultrasharp 24 inch 1920X1200 monitor. Everything that I play was still holding up really well but was showing signs of slowing down. I upgraded to the solid state drive and the 980 GTX graphics card in December, and the rig is right back as 1920X1200 60+100 fps again. Game on my brothers!

Branden_Lucero (07:13 AM, February 18, 2016)

i can find a 6700K as low as $321 as i type this. turns out, the 6700K had a shortage which caused anywhere from a $50-60+ price hike. they are suppose to be $349 as listed by Intel. therefore, i wouldnte recommend getting this processor until it returns to normal or less pricing.

Ares-the-Great (01:38 PM, February 4, 2016)

So, the 3770k is $450, yet, the 6700k, which is more powerful and also newer, is only $400 ($50 less)??? That means that either Intel needs l=to lower the price on the 3770k, or I definitely won't be the one to buy it.
