Can't compete with that PPD, but I made it into the [H] top 10. On track for 1B point month with the extra push from the challenge.
Maybe we will move this summer and I'll install 20kw of solar. :D
I have two GPUs that I would consider full time (4090+4070). My dad nd sister don't leave their systems (which I maintain and upgrade) up 24x7. If I get all right WUs, I might just hit 50mppd output during that week.
Electricity is just too expensive to add any more at the moment.
I fully expect to drop out of the top 10 PPD when the competetion starts. Going to try and add a 4th 40x0 card when I rebuild my dad's computer next week.
I'd say go with 1-2 4070ti. Honestly that is what I would do over my current 4090 setup.
1x 4070ti is almost 2x the ppd of a 4070 for $200 more. 2x 4070ti is going to be 1.5x the ppd of a 4090 for the same price.
