they could've released a better ga103 to desktop,not just duds.

Only bigger Die that indicates what exactly? All other characteristics similar... Anyway, since I have X570 M/B, only for the new 5600/5800 with 3DX, 2 SSDs with PCIE 4.0 interface and perhaps a PCIE 4.0 GPU I would consider. All together will do some slight difference for sure. But already being on a decent PCIE 3.0 GPU and 2 Samsung 970 EVO Plus 3.0 SSDS, and of course a normal 5600X, makes me think won't worth it anyway.
