Hello, so i currently have a GTX 1060 6 GBs paired with a ryzen 5 2600 and 16 GBs 3000 Mhz, Apparently the ryzen is stronger than the GPU and is causing a bit of bottleneck, so i decided to upgrade just a bit with a GPU from the previous gen, im not rich and the GPUs are very expensive...so i was thinking something like a 1070 GTX or RX 590, right now...which one is better? also, I live in south america and those are...affordable, the new gen, such as the RTX are like 2 or 3 times more expensive, so please don't recommend me those
