Help with quiet gaming htpc build to fit existing case.

[spoony77]

Hi people
I have acquired a gd07 from silverstone and I have a corsair 620 psu and a spare ssd already.
I need a motherboard, cpu, ram and graphics card only to run modern games quietly at 1080p and 60fps.
Max budget of £300 if possible no preference to intel or amd.

Any help appreciated.
Thanks

Dayz, tomb raider, gta v?
Corsair hx 620 modular.

Thanks for the advice guys.
Ive been offered a cheap z77 motherboard by asrock that reviews well for £30 so this has thrown up some new possibilities as well
