With Vega prices through the roof, my option is to get a gtx 1070 or a used 980 ti, (But I only have a 500w psu), Im waiting for either christmas, or my birthday (mid february) Im relatively new to the pc world, (not really) I built my pc last christmas, and I was pretty dumb I guess to upgrade my cpu 2 months later because I thought Id be buying a gpu soon, I have an i5 7500, do you think that might bottleneck a gtx 2070 or something?
