That was me - sorry. I just wanted to quote part of your post and must have hit the wrong button, as it was already past midnight here. Honest mistake on my part.
Regarding the content - yes, many used Intel i7 K cpus go for insane prices (on both sides of the pond).

I'm not "buildzoid", KingPin or Igor Wallossek, but from my ~20 years in dealing with PCs and OCing, when it comes to filling up all RAM slots there are several things to consider assuming we are starting with near price and capacity parity:
4 > 2, therefor 2x the amount of possible trouble (DOA, partial defects)
4 > 2, higher chance of getting a total lemmon when it comes to OC
more "strain" on the memory subsystem, with a higher number of sticks
higher memory capacity of a stick usually means lower OC potential. That usually applies to "high density" sticks, with atm go up to 32-128GB. 16GB sticks are an old hat nowdays and are sold at up to 4400MHz from factory, where as 128 sticks anly go up to around 3000MHz max imo.
2 sticks leave room to grow, though it seems unlickly that you 'll need to expand to 64+GB with that system and usecase.
