Not really. Same architecture and basically same performance per core. The old piledriver\bulldozer architecture doesn’t really offer good performance per dollar. Just keep your 6300 for now and look into a mobo upgrade and cpu upgrade. If you live near a microcenter check out their bundle deals. If you want to stay with amd ryzen would be the way to go. Or an intel i5 7600k or non k model. The 1070 is a solid gpu, your bottleneck would be your cpu. Even with an 8370 i still believe it would bottleneck the 1070.
