CPU boss is full of shit they have no idea wtf are they talking about: You people need to use real life tests like USERBENCHMARK http://cpu.userbenchmark.com/Compare/Intel-Core-i7-6700K-vs-Intel-Core-i7-4770K/3502vs1537

In the 'real world' section the 6700 wins literally every test though. Uses less power too. I have pc's with each and the 6700 easily outperforms my haswell pc's.

Was wondering the same exact thing, what's up with the score, BOSS?

I don't have a z87x anymore I have a z97-ws quad strength graphic 4 way motherboard
Dragonsnap (02:57 PM, July 24, 2016)
The Z87 Chipset and it's CPU has 16 PCIe lanes, so you can only have up to 2 GPUs in x8 mode, unless you have a PLX-chip board. That being said, I'm sure the 970 in 4-way SLI would be horrible from a scaling point of view, and would be bottlenecked by the 4770K anyway.

Can the i7 4770k handle 4 gtx 970 sc if so please leave a comment and my power Supply 1200w 80p gold and my motherboard is a z97-ws quad strength graphic power motherboard
Mugsys RapSheet (03:12 PM, June 20, 2016)
Compared my 4770k to a 6700k. The 4770K wins every category, scores 8.3 (vs 8.1 for the 6700), and at the end, declares the 6700 as "the winner"???

https://www.youtube.com/watch?v=WrjwaqZfjIY single core performance SUCKS with 6700k, AND OC'ing it only makes it hotter and unstable with a shorter life span. Keep your 6700k in your office.
Geek Gamer (05:21 PM, June 1, 2016)
CPUBoss is dumb 6700k is 4.0ghz and turbo 4.2ghz not 3.5 and 3.9 thats 6600k i5
Andrew Avantgardian (03:25 PM, February 16, 2016)
on top of that people who buy i7 CPUs usually have a decent dedicated videocard
Osama Kareem (04:18 PM, December 23, 2015)
4770k is better for price than 6700k the only difference is the 6700k has 14nm manufacturing process and HD Graphics 530
