First gamingish PC Build (UK)

Hi, thinking of building my first PC. Would be for general use but i would also like to be able to game on it. My budget is about 450 GBP. Any advice, suggestions and improvements would be very appreciated.

Heres what ive got so far:

Amd Phenom II X4 965 black 3.4 GHz (70 GBP)

ASRock 960GM/U3S3 (43GBP)

2X4Gb DDR3-1866 RAM (whatevers at time of purchace by a decent company) (30 GBPish)

Kingston SSDNow V300 series 60GB (44GBP)

Asus Radeon HD 7770 (116 GBP)

Corsair Builder 600W 80 PLUS certified ATX12V power supply (53GBP)

CiT Vantage Midi Mesh Gaming Case (36GBP)

 

Not sure what to do about storage. Is the SSD necessary or should i just go HDD to hold all my music?

 

Get 1600MHz ram, performance difference is minimal.

SSD isn't necessary if you're trying to build gaming oriented PC. It would only help with loading times, but not FPS wise.

I woul got for a 1TB HDD and 8gb of 1666mhz ram 

i would also put a bit more money in the graphics card and maybe get a 7850 asus make a realy great one 

but this ones a bit cheeper on sapphire is a good brand
