Looking to build an energy efficient PC for everyday use.

No Gaming or video processing.

Just wondering if anyone has experience of the intel g600 series, the low TDP ones such as the G645T http://ark.intel.com/products/series/53254

I will be using highish end components including DDR3 and Sata 3 (6Gbts) SSD's in Raid to get max performance. Will be installing win 7 Pro O/S

Already have a 330 atom board with DDR2 and Sata2, which isn't quite cutting it for me.

Any thoughts?

Thanks in advance

Phil
