upgrading my pc

[saneeras]

Hello everyone!
I want to upgrade my pc.Current specs:

Intel i5 760
Gigabyte P55A UD3R mobo
Zotac nvidia gtx 760
corsair 2 x 4GB 1333Mhz RAM

I want to buy intel 5690K cpu with z97 mobo (please suggest some).
Should I buy another gtx 760 and use it in sli or buy another faster card. so I dont need to upgrade graphics card for at least 3 years ? which will be more economical?

Will upgrading RAM result in better performance ? I heard upgrading from 1333 to 1600 or 1800 results only in 2-3 fps increase

playing games like assasins creed, battlefield, call of duty and total war series.
Thanks

CPU: Intel Core i5 4690K
Motherboard: MSI Z97 Gaming 5,Gigabyte Z97X UD5H or ASUS Z97-A
RAM: You can stick with your current RAM,but I suggest getting new from manufacturers like Corsair,Crucial or Kingston. Corsair Vengeance 2x4GB @ 1600 MHz and Crucial Ballistix Sport 2x4GB @ 1600 MHz are my favourites.
GPU: You can't beat an R9 290,because it's the card with the best price/performance ratio.XFX R9 290 Double Dissipation or Sapphire R9 290 Vapor-X/Tri-X are my recommendations.
What PSU do you have?

what is the purpose of this build if its for gaming you dont need an 8 core i7 processor and the z97 board will not support the processor it has lga 2011 socket.... so if you are building this for gaming purpouse get a i5 4690k and a z97 board.
for motherboard i prefer asus or gigabyte...
upgrading ram will not boost your performance but if u are into animation or rendering then yes more ram with higher mhz is better.
sli is not the best solution sli have its disadvantages if u have the cash then go for a single strong card like gtx 780 or gtx 780 ti ..

I think 2 gtx760 are faster than single r9 290X

my main concern is will 760 sli be able to run games for another 3 years? 760 sli performance is great but wat problems will i have with sli?

psu is 600W coolermaster, but i will upgrade it too (suggestions?)

Get a single R9 290X. You will encounter less problems when using a single card than using 760 in SLI.
Also,SLI isn't really needed unless you have 2 monitors.
What is the exact model of your PSU?
