Looking on eBay completed transactions:
- z790 Ace, lowest at $250 before shipping but $350 ish seem like a reasonable average
- z790 Dark Hero, working lowest seem to be $450 area
- z790 Hero, lowest seem to be $300 area but I seen closer to $400, some "new" closer to $630
So. $800 for Dark Hero and Hero combo sounds fine based on eBay pricing. But for the Ace combo, I would drop it to $700 to $750.
BUT
CC got a Ultra 7 265KF with Z890-S board and Teamgroup Vulcan 32GB for $950 before tax. So in BC that's about $1065 including tax. If I add new RAM to the $800, I'm at $1300.
ME got 9800X3D with B850 board and 32GB of Teamgroup 32GB for $1225 before tax or $1372 with tax (12% in BC). Go with the X870 combo, it's $1350 before tax and $1512 with 12% tax.
If I'm $200 within a 9800X3D, I'm going to with the 9800X3D combo. Yes, your boards are objectively higher end but personally I don't really care because I run at default speed and only interested in slight OC with water cooling, at long as the board isn't shit tier stuff, medium tier works fine. Looking at benchmarks, a 9800X3D combo would perform better or the same as 14900k but with the benefit of Zen6 coming down the pipeline.
