u will only be able to play on ultra and that'll be pushing it and u will have to overclock it to get passed ultra which will burn it out if ur not careful.

a 6870 should be able to handle d3 on any settings, provided you are only using a single monitor. 
 
unlike first person shooters, 30 fps is perfectly fine for D3, since you won't be needing any twitch reaction moments.

yeah thats what i would say but i "heard" that they might be patching in high res textures in so idk that might play a factor but yeah itll play fine and look nice either way
