DDR4 RAM kit for i5 6600K and GIGABYTE GA-Z170XP-SLI mobo!

[dollar5474]

Hello Good People,

I am planning to build a gaming rig. I was planning to use DDR3 on Z97x-SLI with i5 4590 however after the Skylake fever I am pretty much confused!

Please note that I'm from Bangladesh and here brand availability is very limited and also the price is high in comparison to U.S.

>> My First question is Skylake, Z170 and DDR4 is really worth it in light of performance per price?
>> And second, if the above is YES then which RAM should I use on the below config:

Also, if I use a DDR3 Z170 mobo with DDR3 kit, will there be any significant under-performance in contrast to DDR4??

Sorry for the long post!

Thanking you,
Dollar

If you are worried about price to performance skylake is not the way to go. It is significantly more expensive for the performance increase over Haswell Refresh.

Skylake is not worth it right now. Maybe later when the prices have dropped a bit, but not now. Also availability is bad (probably the cause for those high prices). You will also need around DDR4 3000 to make a difference in performance compared to DDR3.
