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
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
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.
CPUBoss is dumb 6700k is 4.0ghz and turbo 4.2ghz not 3.5 and 3.9 thats 6600k i5
on top of that people who buy i7 CPUs usually have a decent dedicated videocard
4770k is better for price than 6700k the only difference is the 6700k has 14nm manufacturing process and HD Graphics 530
