If it's out of reach with a £200 920, it's just as much out of reach with a £200 950. Intel has no plans to release any processors on 1366 that'll be cheaper than the 920, indeed they might not even release a replacement for the 920 as there's a clear overlap with the equivalent 1156 i7 CPUs at this price and performance.
Exactly. I see no logical reason for Intel to release anything new under £300-400 for LGA1366 as it's an enthusiast platform. Where's the business sense in them releasing cheap processors for this socket so that enthusiasts can just overclock them rather than buying a more expensive processor to start with?
