[LAU] another cpu question

Hello all, I may be putting together a box dedicated just to act as a multitrack effects unit - without planning any recording. The effects stack will for most channels most likely look like this: reverb, delay, EQ and maybe one of flanger, chorus or rather seldomly compression. Anyway, just the classics, planning so far to only to install the calf and invada lv2 packages. Though I am open for recommendations here, too. And of course I am looking for a suitable effects host/rack. However, I do suppose, the reverb will be the most cpu consuming item and I am wondering, what feature an a cpu should I be primarily looking for? I guess, for effects, especially reverb, the floating point performance will be paramount? As HT generally has a bad reputation for audio, currently, the AMD FX-8350 is on top of my list, as the floating point preformance is said to be rather good and lots of cores should be ideal for running lots of effects in parallel - though unfortunately not every core does have its on FPU. As it is not going to run 24/7, the insane energy consumption is somewhat acceptable. But, beeing no coder, I may be completely off track with my conceptions here, so I am asking for some more insight or alternative recommendations, maybe even with a short reasoning Thanks Ede
