Suggestions on this build

So, are we all in agreement on the following?

Case: Corsair Graphite 760T (Windowed)
Motherboard: ASRock Extreme 4 (Extreme 6 is way more costly in Estonia)
Processor: Intel Core i5-4690k
Graphic card: MSI Radeon R9 280X (we discussed this last night. He will only be gaming on one 1080P monitor)
SSD: Samsung EVO 840 240GB (Take the $ saved on the GPU and throw it at storage)
HDD: Western Digital Caviar Black 1TB/2TB
Processor cooler: Cooler Master Hyper 212 Evo
RAM: Kingston HyperX Fury (4x4GB) (I'd go with a 2x8GB 1600mhz cl9 kit personally)
Fans: Corsair AF 120mm/140mm

I like 2x8GB as well... leaves room for an upgrade if needed for some reason. Otherwise, looks good to me.

I like the build and second the 2 x 8G of Ram. What PSU though?

How do you guys feel about something in the 850W range to allow for SLI/XFire in the future? He seems ok with a cheaper PSU.

EVGA SuperNOVA 850 G2?
A bit less expensive XFX Core Edition PRO850W. 850w may be a bit overkill but if overclocking the two 280x gpu's the extra wattage is probably a good idea.

well there is that post i did, where Sammies TLC out lasted other brands MLC. i think sammies MLC was the only one that out lasted the TLC though.

Exactly the article(s) I was referring to when I mentioned it earlier.
