my advice would be to ask in June...New cards are hitting the market then and it will affect the prices of current models
Also the gaming components market changes regularly and prices vary...there is no point in asking right now as something might become cheaper and a better choice in 6-8 weeks time.
General pointers:
- Building a system with an i5 but a 980Ti card is a but contradictory. It is a high-end card designed for high resolution gaming (not 1080p, standard HD) Usually it is advisable to pair high-end with high-end, in this case an i7 processor
- You don't need to stick a Corsair H100i on an i5...it is unlikely you will overclock it that much and the thing is super loud too. A Noctua DH-14 or beQuiet Shadowrock Pro will do as good or even a better job and whisper silent and cost a whole lot less too
- 1400 quid build and no SSD? No, you need to reconfigure that you have at least a 256GB SSD for boot, key progs and main games
- 850w PSU...are you trying to power a minor city? For single GPU gaming builds 600w is more than you will ever come close to consuming. If you get an EVGA G2 for example you can even comfortably opt for the 550w - 650w version and have plenty of headroom up
- The Asus Hero mobo is...ok...but there are simply better offering by asus even and by MSI or gigabyte at lower prices
- You don't need 3000Mhz ram as you won't ever feel the benefit over plain 2133 or 2400 Mhz sticks, saves money again
You also don't have a screen, a mouse, a keyboard, a mousepad, a headset and operating system etc in this budget? Is it safe to assume you have another 400 or more spare for that?
Here is a build that crushes what you posted for a lower price...spend more time and an even beter build could come out of that money:
