This will be my first time in building a PC. I know the necessities of building a pc like a CPU , Decent DDR3 ram etc. But I'm looking to build a decent Gaming PC for £350-£400. I want this to be able to run games like league of legends to world of tanks at a smooth pace. So I just really need help with what to get such as what type of processor ,graphics card and ram and how I know if its all capable of being put into the same motherboard just so I don't screw anything up. This isn't meant to be a pc to run things like Battlefield 3/4 . Thanks in advance :)

*** Update***

I've been doing some searching for parts and this is what I found it looks decent to me but I haven't really done any research on the parts.

Here they are:

AMD (Piledriver) FX-6350 3.90GHz (4.20GHz Turbo) Socket AM3+ 6-Core Processor - £79.99

8GB Mushkin Enhanced BlackLine Frostbyte LV #996988 (2x4GB) 1600 (PC3-12800) 240-Pin DDR3 SDRAM CAS 9-9-9-24 1.35V - £54.99

GIGABYTE GA-F2A55M-DS2 AMD A55 (Socket FM2) Micro-ATX Motherboard - £29.99

PowerColor AX6770 1GBD5-H Radeon HD 6770 1GB 128-bit GDDR5 PCI Express 2.1 x16 HDCP Ready Video Card - £40.00

650W ARIAnet ACE Xtreme Series Power Supply - £18.95

Arctic Cooling Freezer 7 PRO Rev.2 Quiet CPU Cooler - £15.53

Sharkoon VS3-V Green Black Midi Tower Gaming Case - £22.75

1TB Seagate Barracuda ST1000DM003 3.5" SATA III Hard Drive - HDD - £35.00

Tell me what you think.
 
That build does not work

The processor fits an AM3+ motherboard

I dont know where you got prices from but something like this

Athlon X4 750K
FM2+ motherboard [ the + means it can use newer upgraded cpu's]
2 x4 gig of RAM
Radeon 7770 graphics card

would be the basis for a good cheap gamer
