170 with 391 attack 1959 dex buffed is 61k.

It also depends on your level, to add to what williamme said. I'm just going to assume that you're level 170 and have your range-affecting skills maxed... given that, it'd probably take around 300-350 att, with at least 60% dex, though probably around 70%. You can adjust that however you want (e.x.: 400 att and 50-55% dex)...
Also, do you mean with or without hypers - it's obvious that you meant buffed, but are you including hypers? If you are including hypers, you can probably wack off 100 att, as that's more or less covered.

[quote=williamme]It actually depends on attack too. When you have a decent DBG and empress set, you can probably achieve 100k range with maybe 50% dex? As for me, I didn't have much attack, so I achieved it at around 80%.

edit: I realize I misread that you asked for specifics. Probably around 400 attack and maybe 60-70% dex (Rough estimate).[/quote]
Okay thank you.

Without any link skills and fully buffed, 463 att and 2800 dex is approximately 100k range.
