Anyway, is kernel 3.17 working fast and reliably (except for the standby issue)?

Everything else in 3.17 is OK, yeah. Not many performance improvements, at least nothing b too noticeable... But I won't use it unless they fix it.

While there are plenty of performance benchmarks I am missing some quality benchmarks here, like frame time jitter, overall rendering quality (which should not be an issue anymore, I hope!), ...? Especially jitter gets annoying as hell with compositing window managers, and it's very much there with e.g. the open source radeon driver:

Especially jitter is a huge issue in my opinion. See for yourself in the data below.
