Help with gaming pc build

[starry21]

Hi everyone, i havnt done much with computers for a number of years and my laptop that i used to use for gaming just doesnt cut it anymore, i was using a samsung np300e5a laptop which ran most games on low settings but i would now like a computer that can run games on high/ultra for a price of around £400.

I have had a look around and decided on these parts:
Sapphire Radeon R7 240 Boost 2048MB GDDR3 PCI-Express Card #57845

AMD (Richland) A8-6600K 3.90GHz (4.20GHz Turbo) Socket FM2 Quad-Core Unlocked Processor #55738

ASUS FM2+ A88X-PLUS Motherboard #60269

Arctic Cooling Freezer 7 PRO Rev.2 Quiet CPU Cooler #20729

GIGABYTE KM7580 Wireless Mouse & Keyboard Bundle #46192

TP-LINK TL-WDN4800 N900 Wireless Dual Band PCI Express Adapter #52680

ARIAnet Goblin Mesh Midi Tower Gaming Case #59672

120GB Mushkin Chronos 2.5" 7mm SATA 6GB/s (SATA-III) Solid State Drive #59734

120mm Cooler Master SickleFlow Green LED 3-Pin Fan #50011

I already have a 1tb samsung sata hdd, 2 x sata cd rw drive and a 700w win power adk 700 power supply.
the total cost of all these parts comes to £362 from www.****.co.uk
the # number after each item is the product code from ****

Would these parts all be compatable and would it be a good enougth set up to run games such as Diablo 3 and Call of Duty Ghosts on high/ultra

Ok, at least I know not to buy them parts then, what sort of setup would you recommend for playing diablo 3 on high settings?
