Core i7 4790k vs 6800k windows 7

[MattO1973]

I want to build an Intel powerhouse but I want to run Windows 7 and not sure if the Core i7 6800k or the core i7 4790k will continue to get support from Microsoft, I understand Skylake and Kaby Lake will not, but unsure about Broadwell E

What about 5820K? Its a bit faster than the 6800k as it overclocks better. Its got a better price also. Win win.

It's my understanding that the 5820k is a little slower than 6800k at stock clocks 6800k = 3.4 and 5820k = 3.3, my goal is to get the newest and fastest that will stay compatible with windows 7

Yes lower clocked at stock but able to overclock more than the 6800k. Plus the price is why tomshardware has the 5820k rated best. If you hit the link as then the red arrow you will see the 5820k takes best CPU. They all but the 7700k with kaby lake are compatible with windows 7.

For consumers Intel will provide Windows 7 support for CPUs through Kaby Lake, including Core i7 6800K and i7 4790, until 2020 [a Kaby Lake CPU will be required to be in a 6th generation Motherboard that has a BIOS update to run Kaby Lake, after sometime projected to be mid 2017 when MS is suspected to upload software to disable support for 7th generation motherboards, it is the 7th generation motherboards that Windows 7 will not have support from MS]. After that date, on 6th generation motherboards and earlier just keep your old drivers for old hardware, and use drivers from manufacturers for new hardware and use a good anti-virus, such as VIPRE or other good program, and keep you system clean using CCleaner [ you should be using that latter two types of programs even now.]

I know the above is a little wordy, however, MS makes things complicated, it seems to be in their nature.
