Greetings, I want to know which gpu you recomend. All of them have same core config based on Pictairn and same memory amount. Only difference is increase in core clock by series. Because of that R7 370 is the fastest. I know that I can overclock HD 7850 to 1200-1300mhz core,and thst makes it the fastest,same can be done with two others, they have almost the same clock range of 1200-1300. But I dont know does this newer rebrands have higher quality VRM and does R7 370 have true DX 12 support(DX 12_1)?(I know that other two have feature level 11.1 with partial DX 12 support). Also I didn't mention all are GCN 1.0.
