I am looking at building a gaming pc using a Sapphire Radeon HD 7870 OC edition.
However, I have seen many threads about black screens, buzzing and cutting out caused by this graphics card.
Are these problems still happening now or have they been fixed?
What you have to take into account is the number of users who improperly install these GPUs or who have insufficient PSUs, for example. You won't see threads by the vast majority of users who don't have any problems.
This is a good GPU. Just install the latest drivers directly from AMD when you install. See below:
Okay I will stick with the HD 7870 and overclock it when I need too.
My specs are
ASRock extreme4 z77
8gb Corsair vengeance
Cooler master 212 hyper evo
Antec three hundred two
850w XFX Pro core (I know its overkill but I want upgrade room)
1tb western digital Caviar Green
