Checked my funds today and to my surprise, I can easily upgrade my whole rig, so forget the phenom 965BE, I'm going to finally join the i5 brigade. High five _o/*\o_ 
So by various accounts, Sandybridge still seems to be better than IvyBridge. What should I do, Sandy or Ivy? If I go for the 3.4Ghz 2500K, OEM or retail? £10 more to get 3 years warranty, or £169.99 OEM 1 year warranty, no box?
And what's up with the prices here, am I missing something? Why is the OEM more expensive for the OEM 3.3Ghz than the retail 3.3Ghz, when the OEM 3.4Ghz is cheaper than the retail 3.4Ghz?
