Thanks for the replies guys !
Yeah the Xeon chips come in around £800 - £1000 here and that's waaaaay out my price range,
I am leaning towards this as my build....
i7-3770K 3.50GHz (Ivybridge)
Gigabyte Z77X-UP5 TH or UP4
G.Skill RipJawsZ 32GB (8x4GB) DDR3 PC3-12800C9
Unless anyone can say a reason to go for i7-3820 3.60GHz (Sandybridge-E)?
The other 2011 chips are almost double so out of my price range but the Z79 boards are about the same price.
Thanks again
Norrie
