Definitely frustrating I'm sure. I like the idea that the benchmarking and monitoring tools haven't caught up to the new chips much better than the idea of a chip which will spike temps though!

So are you saying that it looks like the spikes you're seeing are the norma for the new chips? Any info on whether it's a real spike or a software quirk?
If you get a chance to take more pics or get some benchmarks/reviews in that would be awesome. Interested in hearing more regardless of what you go for. Very cool
