I have an old xfx double dissipation 7870 graphics card.i know from what i have read that i can oc the hell out of the core clock.currently i am running stock.i did oc the memory a bit but…anyway from what i have read i can overclock the core up to 5,000 mhz from 1050?im not an overclock person,but this sounds iffy.i know it’s double diss and all that but still,i am leary.anyone know if it’s worth trying to get better results with gpu rendering?i also learned my so called 8 core cpu is only 6 with 4 virtual cores.ugh…any help would be appreciated.
