I'm going to be upgrading my system (I5-3570K, GTX970, Asrock H61 mobo, XFX TS 550w PSU etc..) to a whole new setup. I'm going to get

Corsair 760t Full tower Case

Asus Maximus VII Hero Motherboard

I7-4790K CPU

2nd Gigabyte G1 gaming GTX970 for SLI

8gb Corsair Dominator Platinum RAM

Samsung 850 Evo 500gb SSD (getting a 2nd one eventually to put in the spring loaded SSD slots in the case wall)

Corsair H100i Liquid CPU cooler

and i'm deciding on what power supply to get, the GTX970 usually has a 500w psu reccomendation but the Gigabyte superoverclocked G1 reccomends 550w, and places like guru3d say 700-800watt reccomended for SLI 970's, so i thought i'd go for an 800 watt psu, but the Corsair AX760/760i is apparently a high quality PSU, being 80+ Platinum and all, so i wondered if that would be enough to Overclock two Gigabyte G1 970's with, although if i do decide to go for 60fps 4k later this year and get either a GTX980 ti or an R9 295X2 would i need an AX860 or 860i? Also, is there any major difference between the 760/760i and 860/860i?

Get this power supply instead, best PSU on the market right now.
Power Supply: EVGA 850W 80+ Gold Certified Fully-Modular ATX Power Supply ($109.99 @ Newegg)
Total: $109.99
Prices include shipping, taxes, and discounts when available

The Corsair ones are good but way overpriced.
750W would be enough for overclocked 970's but the extra 100W will be better for the PSU to run.

That is interesting, although it's technically $139 with a rebate, which is a huge headache to turn in. The Corsair AX PSU's are 80+ platinum, have software monitoring, and has red and black coloring which matches my case a bit better than the black and gold look of the EVGA. So i have a little bit of a hard time believing that an 80+ gold PSU is actually the best on the market when there's good quality platinum and even a couple titanium out now, unless you mean best for the price?

80+ ratings are not everything. Power supply build and performance are critical factors too.
The Corsair AXi series are great, they are build and perform very good. Just like the EVGA G2.
The biggest throwback is their price. The step from 80+ Gold to Platinum is so small, that it's not worth the money. It's up to you actually how much you want to spend.
Don't get me wrong, performance wise both are awesome, it's the price that will be the deciding factor here.

Yeah i know it's not everything, but when you were saying the evga was best on the market i was pointing out that even a 2-3% increase in efficiency is technically "better".

What do you think of this one (coolermaster V850)

http://www.newegg.com/Product/Product.aspx?Item=N82E16817171079&nm_mc=AFC-C8Junction&cm_mmc=AFC-C8Junction-_-na-_-na-_-na&cm_sp=&AID=10446076&PID=3938566&SID=

After rebate it's only $10 more than the EVGA one, it scored 9.7 on johnyguru vs 9.9 on the evga, but this one actually scored 80+ platinum efficiency when tested even though it only says 80+ gold on the box. Both the CM and EVGA are made by good companies, Superflower and seasonic are both real good but i'm not sure which of these two units is better.
