Loosing faith in Apple, need current recommendations for PC for Adobe use

Having been a loyal 25+ year Mac addict I have finally lost faith. I've wasted the better part of this year for a decent update. It's not so much the cost factor than it is buying a machine that it near the end of its life cycle.

For professional use I could get by with just Lightroom, Photoshop, After Effects, and Premier. For video I am a FCP user but am happy to switch to Premier if it means I finally get a new computer and not one that's 400+ days old (current Macs).

I am not a gamer. I don't see much need for a blazing graphics card (my needs are more CPU based).

I would like to spend ~$3000 for computer and 27" monitor. I know NOTHING of PCs.

Does anyone have any recommendations?
