Sandy bridge looks pretty disappointing to me IMO, 10% gain per-clock, and no overclocking unless you buy a K-type CPU. That said, the K-type CPUs aren't much more than the normal chips at least, and the TDPs are good at 95W max, even for the hyperthreaded top i7s, which also retain the lack of chipset and IGP. I perceive it as more of a refresh of i5/i7 which is fine for now but I have concerns about its competitiveness against the upcoming AMD Bulldozer CPUs.
