Would you say that if 2080 is 10% faster than 2070 for $200 more and all they have to justify it is gigarays or whatever it is called ?
I like buying new gen cards too,I'm itching to upgrade even though I have stellear performance on 1080, but pre ordering rtx is just silly unless you absolutely do not care about perf/price.
GTX 1080Ti was like 200€ more than GTX 1080. For almost 50% bump in performance. So, there's that... But when someone is looking for ultimate peak performance, 10% for 200€ is something they don't really care about.
