You could go to Max’s C16 157% would give you about 1.5PBe.
A rtx 4060 would probably handle that. I can’t promise but that would be about 60W in use. Maybe $300.
Now, what would your compression choice get for 60W and $300?
MAYBE 10 disks, 80TB? This is a difficult guess…
So C16 gets 1.5PBe, your cpu compression choice gets 1.4 maybe at a stretch
I hooked up RTX 3060Ti to my current farm with official Chia C4 because proof times resulted in rewards lost.
in comparison to CPU farming what worked till filter halving, I have gained +20W but proof times are below 1s now.
C16 @ 60W in nvtop is around 100W in reality or 14x HDD or at least 250TiB
For my current 1PiB RAW, I would get 1.57PiBe and extra power use. Everybody talks about GPU farming, but nobody likes to talk about wattage. It is a weird coincidence, no? 
Once, they master compression efficiently. I will think about it.
3060 seems a lot for c4 but I only have a small farm so I don’t know
One of you guys should export hdd to UK/England. We have to pay over $10 per TB here. You could double your money buying drives at $2.5 and selling at $5 per TB.
Unfortunately, I was successfully farming with CPU till filter halving despite overdesigned…of course 3060Ti should be higher compression for sure.
With this regular plot format crap changing every year, no lust for replotting again. At end of year, there is possible hard fork of plot format again…then what. Max, NoSSD may get finnally banned from our network…then what.
Compression looks promising, still too young and inefficient.
