The wait for the RTX 2080 Ti Super is killing you? If you already have the RTX 2080 Ti and US$2,000 lying around, why not just take matters into your own hands and build the RTX 2080 Ti Super yourself? It's a risky process that requires you to sacrifices two RTX 2080 Super cards and do some reballing and resoldering work, plus you will have to overclock the VRAM to match the 16 Gbps speeds.
