I'm buying an AMD R9 280x to crossfire with my current AMD Sapphire 7970 OC edition. I have seen many issues with this card from many manufacturers and I'm curious which one is the most reliable to today as all the issues I have seen date back to when the card released. Also, if one card doesn't work well out of the box, like artifacting, but can be fixed easily, which cards are best. It would be cool if people could list the top 2 manufacturers as I'm buying used from Amazon because that will save me at least $50.
