You can sell your 245K and buy this one and sell the ram stick as well if you don't need it I think it will be cheaper for you.
It's OK for my current needs. Don't really want to spend until the 300 series launches so I can see if the 385K is worth it.
My wishlist for 385K:
6+ GHz ST
5.8 GHz MT
HT
AVX-512 (if it's there and can be enabled, even if the E-cores need to be disabled to use it)
D2D, NGU, Ring latencies all fixed or optimized out of the box
L3 cache increased or existing one with reduced latency
Much better IMC that can hit DDR5-10000 XMP Gear 2 without issue
But considering their current state, we probably won't get any of that. Maybe a 100 MHz speed bump on every K SKU if we are lucky.
