Hi,
I've decided to build a PC and after looking around for a while have settled a some parts. However, I have a few questions about some of them and it would also be helpful if some people more knowledgeable than me about this kind of thing look over it and see if there's any way to improve it, drop the price, etc.
The parts I've seen are:
i5 3570k - http://www.amazon.co.uk/dp/B007RUZKK6/?tag=pcp0f-21
Gigabye GA-Z77-D3H Motherboard - http://goo.gl/aoL7U
Vengeance 2x4gb Memory - http://goo.gl/6uxTo
Sapphire AMD HD 7770 GPU - http://goo.gl/4IMw9
XFX ProSeries 450W Core Edition Power Supply - http://goo.gl/T7y5W (Will this be enough?)
Fractal Design Core 3000 - http://goo.gl/fdCv7 ( Is it worth Paying Extra for the Arc Midi?)
160GB Seagate Drive (I have this already)
OCZ Technology OCZ Vertex Plus R2 SATA 2 60GB - http://goo.gl/ahEto (Not sure about which one to get, or whether it is worth paying the extra for a Sata-III Drive, It's only for the OS)
Thanks for any help
