Someone could help me?

DVI-I adapter with resistors? Its really unsafe to keep 24/7 without monitoring temps/wattman to change mem/gpu clocks.

I found on ebay hdmi dummy plug, that would work for me, what do you guys think?

Its cheaper to get display port to vga adapter/dvi-d, and add 3 resistors of 75 ohms to it, like my old 280X worked (with DVI-D to vga adapter), would that work?

thanks
