Is this a good build for a budget of £900 or $1400?

[andrewskea]

This is my build, but i'm not sure if its the best build for this budget of £900 (including monitor, OS and mouse and keyboard.) Is this the best build?
It is primarily for everything and there will be intensive applications, photo rendering (not video) a lot of gaming Battlefield, COD, Farcry and many more.

Motherboard: MSI Z87-G45-GAMING S1150 Intel Z87 DDR3 ATX (£122)
Processor: Intel Core i5-4670K S1150 3.4GHz 6MB Haswell (£190)
GPU: VTX3D AMD Radeon 7870 HD 2GB PCI-Express(£167)
RAM: Corsair 8GB (2x4GB) DDR3 1600Mhz(£52)
CPU cooler: Cooler Master Hyper 212 EVO(£24)
PSU: Corsair Builder Series CXM 600W Modular 80 PLUS Bronze Certified(£59)
HDD: Western Digital Black - 500GB(£55)
Case: CoolerMaster Elite 431 Midi Tower(£41)
Optical drive: LG GH24NS90.AUAA50B 24x SATA(£11)
OS: Microsoft Windows 8 64 bit(£70)
Asus VE228HR(£109)
I have not included mouse and keyboard but I'm getting it cheap for £20 for both

Please suggest any changes if necessary or if there any other shops in the uk that provide the product at a cheaper price. If i'm going to overclock my cpu should i invest in a better CPU cooler?
Thankyou in advance

You can buy instead of the 7870 a more powerful gtx 660 ti and cheaper.

That one is used thats why it is so cheap (its still more expensive than the 7870), and how is it better?
I want to buy completely new so i have warranty and higher chance of it working

I think it's worth it.even if its used.It has return policy too.If it doesn't work take it back.
