My 10 cents (due to inflation):
IMHO, increasing the points tier structure from 2M/4M to 10M/25M is a bit much for keeping the same five/ten dollar EVGA Bucks levels. Even though I've already reached 25M points for this month, I do agree with other commenters that the majority of our fellow folders will have a hard time reaching these point totals.
Personally, it wasn't too long ago that I had aging video cards and had to run two desktops for almost a full month to reach point totals, and can empathize with others currently in that position. Luckily, I upgraded to 10XX and 20XX cards that can more effectively produce folding point totals more efficiently with less energy usage.
That being said, I support the three-tiered structure that a fellow folder mentioned earlier. Thanks to EVGA for continuing their very generous program; I can't think of another nVidia-based graphics card company that offers a similar program.
Finally, I personally think the 20XX graphics card prices are overly inflated. For example, EVGA lists their basic 2060 video card at $349, which is what their top-of-the-line 1060 sold for last year. Hopefully, the new folding point structure will take this into consideration, and entice folders to upgrade their rigs at a fair price.
