Is it just Tmax (ie chip stays at max turbo as long as CPU isn't too hot) or is it also measuring power draw or other variables? Asking because I'm pondering building a workstation with one of those cheap v2/v3/v4 Xeons on ebay. Would be great if I can stay near max turbo just by slapping on a good hsf, but it's less appealing if they're gonna drop to base ~2.0ghz clocks every time I throw a sustained workload at them. Goal with this machine is smoother multitasking. The laptop in my sig can do most of what I need but it doesn't stay responsive while recalculating big Excel sheets, batch processing images, etc. Would be nice to have a bunch of cores so it doesn't choke on that sort of lightly threaded stuff. Also wanna do some experimenting with ESXi which apparently is pretty core hungry.
