Any revolution to wait for?

Hello guys, my first time to post here.

I recently started to plan a budget PC build made for gaming and some basic music editing, based on AMD FX 6300 CPU, PowerColor 270X GPU, 2x4 GB RAM (1600 mhz).

My plan is to buy it in the next few months.

Looking for something long lasting (as dreamy as it sounds), I would like to know if there is something really revolutionary in making, new RAM standard, CPU refresh etc. coming in next six months or so, that you are aware of, that is really worth waiting for? Also, any suggestions about RAM maker (Kingston, Corsair)?

Not a native English speaker, so sorry for any mistakes.

Thanks in advance!
