After a year of saving I purchased a Gigabyte 3080ti OC. System 1 year old.
Z390 Gigabyte Aorus Master, Thermaltake AIO water cooled, Thermaltake 1050W PSU, etc etc.
Used 2 x 8 pin pcie cables to PSU.
3080 is only week old. System all stock. Two hours into Elite Dangerous the GPU fans spun crazy...
