It takes a thousand GPUs to make something serious. Everything else is just kidding
Why GPU? BSGS works on CPU.
btw, what's more important RAM or CPU?
I've tried
AMD Ryzen 9 7950X - 4.5GHZ, 16c/32th + 128GB - 4ek on start, reaches 6ek after week
Intel Core i7-11700K 3.6GHZ, 8c/16th + 128GB - only 2ek, no growth
Intel Core i7-11700K 3.6GHZ, 8c/16th + 64GB - around 1ek, no growth
