It depends on your lvl and what you do mostly. I only have 105 vit. So I only have 700 base hp or so. But with gear I can go 1300.
How do you survive any bosses? I'm running around with 1,200hp and that's barely enough. Distract helps a lot, but when a boss cloaks i am no longer any help.. And to the op, the best DPS is a mix of dex and str, if you went full with either one you would suffer in DPS. Most bosses in the game have a really high defense, so if you want to actually hit them and do damage use a little dex. My current stats are 450(545) 50 100 175. I'd use more dex but i get enough attack from my gear.
