You don't have benchmarks on either, so your assumption is just that. But based on what we know, the XTX should be SIGNIFICANT faster than the 4080 in raster, ESPECIALLY if you get an AIB card that pumps up the power to 450 watts!

For RT, we will have to just wait for actual numbers. As for DLSS? AMD has FSR, and while DLSS might have a SLIGHT edge in overall quality, you have to strain to see the differences in most of the comparisons I have seen. Buying overpriced hardware because of a SOFTWARE feature is ludicrous in any case.
