Recently did a little build upgrade/refresh with a CPU upgrade and cooler upgrade.
Went from 7800X3D/U12A with G2 fans to 9850X3D/D15 G2 and added a Thermal Grizzly contact frame when I had it apart. The rest of the build is unchanged.
Gaming wise, not huge but notable uplift in FPS in the games I play. Roughly 15-20% in average FPS, but significantly better 1% and 0.1% lows. In day to day use and more productivity focused workloads, however, the 9850X3D is substantially faster than the 7800X3D.
Only downsides to the upgrade were the daughter board with the 3rd M.2 slot doesn’t fit with the D15 G2 installed so I had to relocate it externally to a 40gbps external USB4 M.2 enclosure. This is fine as this drive is used primarily for backing up family photos and various documents. Also had to ditch the factory heat spreaders on the Corsair Vengeance RGB, but temps are still great without it and I wasn’t really using the RGB anyways.
