I was hoping that OCUK would have these by now.
If you mean the E6500K then no European or US retailer will touch them Intel won't honour any warranty claims made outwith the market the product was sold for. Also Intel will likely warn big EU and US (r)etailers against grey imports.
If it's the E6300 then I'm not sure why OcUK don't have them as everyone else does. Send them a webnote and ask?
