Please rate my pc and give me an idea on what should be upgraded or changed.

[darkycombat]

CPU: Intel i5 2500k
GPU: XFX Radeon 6850HD (planning on getting a 6gb 1060 or saving and getting 2 8gb 480's)
Mobo: Gigabyte Z68A-D3-B3
Memory: A-Data 4x2gb(getting G.SKILL Ripjaws X Series 8GB (2 x 4GB) DDR3 2133)
Storage: Seagate ST31000524AS 1TB and also getting a Kingston SSDNow UV400 240gb
Case: Apevia X-Trooper Jr Gaming Case (getting a Rosewill Stryker M)
My build is around 5 years old now and I want to upgrade my parts but I'm not too experienced with how to. Ideally I don't have to upgrade my hardware for another 5 years but that's not very likely considering the graphical improvements in games and stuff like VR.

Get a 6GB GTX 1060 and save the rest of the money to move to Sklylake or Kabylake i5.

Get a decent CPU cooler and overclock the living balls off of the 2500k. Even by today's standards, it's a fairly strong CPU.

Get the single gtx1060. Multi-GPU is in a very weird place right now.
