[kaolaaan]

Hi all,
Just wondering if you could give me some advice on some money I could save on my gaming PC as it is around £900 at the moment which is quite big, so could you please help me if there is anywhere I can save!
I have gone for:
i5 4570, 1150 Haswell
GTX 670
Gigabyte GA-B85-HD3, Intel B75, S 1150
600w Corsair Builder Series CX
1TB Seagate
2x4GB Corsair DDR3 Vengeance
Corsair Raptor M40 Gaming Mouse
Corsair Raptor K30 Gaming Keyboard

I am mainly going to be using this PC for gaming on the latest games and also I use photoshop and after effects ALOT. So if there is anywhere I could save money can you throw out some suggestions please!
Thankyou!
