I'm hesitating between this one and the 9800x3d, but having a 5900x, I'm used to having 12 cores, so it's hard to go back to 8. What's more, I do more production than gaming, so the 9950x3d is probably better suited to my needs. On the other hand, even top-of-the-range MBs can't handle 2 m2 gen 5, the asus rog 870e, one of the best, does have 3 m2 gen 5 slots but only socket 1 has its own dedicated line with the cpu, so if socket 2 and 3, the gpu switches to 8x, which is really rubbish, so you have to switch to gen 4 for a second m2 that goes through the chipset. So to sum up > 1 gen 5 on socket 1 and a gen 4 on socket 4 so that the m2 + the gpu work at maximum.
