What should I upgrade on my pc?

[deadpresidents]

This is my current gaming system:

1 x Intel Core i7-4770K 3.50GHz (Haswell) Socket LGA1150 Processor - Retail
2 x MSI HD 7950 Twin Frozr III Boost Edition 3072MB GDDR5 PCI-Express Graphics Card
1 x Gigabyte Z87X-OC Intel Z87 (Socket 1150) DDR3 ATX Motherboard
1 x Samsung 250GB SSD 840 EVO SATA 6Gb/s Basic - (MZ-7TE250BW)
1 x 1TB HD
1 x Samsung Blu ray rewriter
1 x Patriot Viper "Black Mamba" Generation 3 8GB (2x4GB) DDR3 PC3-17000C11 2133MHz Dual Channel Kit (PV38G213C1K)
1 x Thermalright True Spirit 140 BW Cooler
1 x XFX ProSeries (XXX Edition) 850W
1 x Fractal Design ARC Miditower R2 Side Window
1 x QNIX 27" 2560 x 1440p IPS screen

I am looking to switch to the best clocked 1080 as I dont really overclock, I'm also looking for a new monitor with GSYNC however I'm torn over a superwide/dual monitors or one 27" and a new large capacity hard drive too.

Which upgrades would put the system ahead?

CrossFire and SLI don't perform as good as a single very strong card. So i'd suggest cutting those GPU and switching for a GTX 1070 or a 1080 - since you want GSync -
Any lesser card probably won't run at 1440p decently.

MSI and Gigabyte offer very good overclocked GPUs, so you won't have to worry about squeezing out some more perfomance out of your card.

If you want to, maybe some 2x8GB RAM? That'd be nice too!

With both changes, you'll see a good change in your gaming experience, go for it.

What ram should I get? DDR3?

What ram should I get? DDR3?

You have two options:
Pick two 8GB DDR3 1600Hz RAM.
Buy both in the same kit, (same speed, same brand ) that way they'll work properly in dual channel.

Or

Pick four 4GB DDR3 1600Hz RAM
Buy two kits of the same brand/speed for all of them.

The former is your safest option ( and will perfom nicely ), you'll maybe get some more speed with 4x RAM but that isn't always worth until you know a little more about latency and timings.

But yeah, go ahead with DDR3 1600Hz RAM, don't buy any with a higer speed because your CPU doesn't support them, so you'll be paying more for receveing less.
