i'm just gonna go with GPU set up actually.
i went ahead and bought a few 3070 GPUs. I'll buy more to have 6 of them.
Along with those,
Intel Xeon L5630 2.13GHz SLBVD 12MB LGA1366 Quad Core Processor MATCHING PAIR
Supermicro X8DTE Dual Socket 1366 E-ATX Motherboard DDR3 SATA2 w/ I/O Shield
Both are refurbished/used. like $60 for both.
Do you guys think this is the best combo?
Why Intel Xeon L version? Are you planning to use the motherboard for something else? If no then go for Intel Pentium CPU, they are the cheapest since you won't be needing the CPU horsepower
