> Base clocks are irrelevant on desktop, it's not Sandy Bridge days anymore

Reading this makes me feel like I need to build a new PC now lol. Any idea what percentage of desktop PCs are still on Sandy Bridge?

Good statistics about the current install base rather than market share are hard to come by. The Steam Hardware Survey is a decent source when you're looking at desktop PCs, because there's pretty strong overlap between desktop PC users and gamers. Slightly more than 25% of machines measured by the Steam survey don't support AVX2, which means they're pre-Haswell on the Intel side or pre-Excavator on the AMD side, or a newer but low-end Intel model. (Those recent low-end Intel chips that have AVX2 disabled also tend to have Turbo Boost disabled.) It's plausible that Sandy Bridge and earlier may still account for 10+% of gaming desktops.
