14900K is not good for gaming, you'd better get 9800X3D.
Any modern mid-range CPU will work fine for most coding tasks. Unless you're doing heavy compilation or running multiple VMs, even a Ryzen 5 7600X or ...
@elizabeth_ben 9800X3D is announced, about 8% improvement over 7800X3D.
Maybe some accessories bundle deals at Black Friday/Cyber Monday.
Which RX 7900XTX do you recommend?
Check Newegg Black Friday deals. There are plenty of good laptops on sale.
I guess price will be dropped after 9800X3D released.
Next year Quest 4/4S released, then you will get rebate on Quest 3S.
Legion GO or ASUS ROG Ally X?
Maybe $100 off.
