I have the sapphrie r9 390 and it's great. I have no issues other than like little jumps on higher end games like Wither 3 and even then I have it maxed with no v-sync. I was a little worried I was going to have problems, but I have none except on battlefield 4 where the game crashes when I go to the loadout screen to change some classes. But, that's literally the only problem I have ever had.
