First is it worth it to upgrade to ddr4 ram, just bought 2x 8gis ddr3 over a year ago. Personally I want to save money but no point not to buy ddr4 if its something that I'll want to upgrade in the future.

Most CPU's I buy will come with a fan right?

Besides socket type do some motherboards and cpu's work wanky together if brands dont match? Is it okay to buy what ever is on sale with motherboards or does quality/brand make a difference per cpu.



Also if anyone has any black friday sugestions that would be nice, so far looking at an i5-4690K (or i5-4690) and an i5-6600

.. to upgrade



Most of them, but I recommend getting this anyway: https://pcpartpicker.com/part/cooler-master-cpu-cooler-rr212e20pkr2



Enjoy.
