Specs for new gaming rig - feedback and suggestion welcomed

[Sithicus]

Hello. I'm planning to replace my old PC with new system as I have not upgraded it in last 2 years and it's starting to slow down a bit. Recently I've had a problem with GPU overheating and my machine would restart after playing a game for few hours - I've been plying Dying Light in 2560x1600 with all options on max.

I live at the moment in UK and I'm planning to buy a new rig in second half of March.

Here are my current specs:
CPU: Intel Core i7 920 @ 2.67GHz (overclocked)
MB: EVGA X58 SLI Classified
GPU: EVGA GeForce GTX 680 FTW (overclocked)
RAM: Corsair Dominator, DDR3 PC3-12800 (1600), CAS 9-9-9-24
HDD: 1 TB Western Digital 1TB VelociRaptor + WD WD40EFRX-68WT0N0 4TB
PSU: Cooler Master Real Power Pro1000 RS-A00-EMBA 1000W
Cooling: Antec Kuhler h2o 920
Case: CM Stacker 830 NVIDIA Edition
Monitor: Dell 3008WFP (2560x1600@60Hz)

Here is what I'm thinking of getting:
CPU: Intel Core i5-4690K (overclocked to 4.4 GHz)
MB: EVGA FTW Z97
GPU: EVGA GTX 980 FTW
RAM: Corsair DDR4 Vengeance LPX Red, PC4-21300 (2666) Non-ECC Unbuffered, CAS 15-17-17-35, XMP 2.0, 1.2V
HDD: I'm keeping the existing HDDs, not 100% sure about upgrade to SSD
PSU: Corsair HX1000i 1000W OR EVGA SuperNOVA 1000 G2 80+ GOLD 1000W
Cooling: Corsair Hydro H100i GTX 240mm CPU Cooler
Case: Coolermaster Stormtrooper Full Tower

So what do you think?

(Edited: MB changed)

You need an 1150 socket motherboard for that CPU and DDR3. And you are spending dumb money on a PSU you dont need. Even SLId youd need no more than a 750-800w quality PSU. For a single 980 550-600w is plenty.

the 4690k is a 1150 pin cpu and wont work in that mb you need a z97 1150 mb.
myself i hold off till skylake drops at the end of summer.
the skylake are the replacement of the haswell cpu and use 1151 pin mb and 100 ser mb chipsets.

So EVGA FTW Z97 instead of EVGA X99.
Any advice on RAM?
