My Demon Hunter character finished Nightmare at level 52 or 53 without using the Auction House at all, ..Big Mistake!! I was 9K DPS, 1348 Armour with only 12 Life Regeneration. Then I tried the Auction House purchasing armour and weapons costing anywhere from 20K to 50K gold only, ..then my DPS went from 9K to 26K, life regeneration went up to 170 per second. Now Hell Act 1 and Act 2 felt Easy (I don't want it too easy also though). And I still have some crappy armour left. I don't wanna buy too much and make my character too Invincible so I could enjoy a little challenge. Now I don't even care about the droppings, and the blue and yellow Elites of Hell Act 1 and 2 are fairly easy (not too easy, but very fun challenge). So many cheap weapons and armour (but very effective) at the Auction House. They cost anywhere from 5,000 to 100,000 gold (fairly easy to farm). I'm also running Diablo 3 at 1080p Highest setting, high shadows with Anti-aliasing enabled but No V-sync with my OC'ed GTX 460M. I get anywhere from high 50's to 60-75-80 FPS average. When I get my M17X with the 680M I will surely enable V-sync. Now I'm really enjoying Diablo 3 (level 58 at the moment in Hell difficulty Act 2).
