Hi all, I have now decided to upgrade my system as I realised after I posted about overclocking my check, that I have in fact got one of the original I5 Quad Core Lynnfield chips the 750 @ 2.67 so the chip is a few years old and unsure how it will overclock.
I decided to build again so I put this spec together. These are the only components I need:

Also I have been reading that the Z77 chipsets have an issue with sound cards on PCI, so the only thing I was of changing was the mobo down to a Z77-D3H as it is cheaper and put it towards a PCI-E sound card. Also I have a 19" samsung monitor running at 1650 x 1050. Any advice is appreciated. Thanks.
