Built my son's first gaming PC 2 months ago. Figured it would be cheaper around Black Friday, but the prices were reasonable enough that we didn't wait. Turned out to be a huge savings to buy that fast DDR5 in September.
I wish I would have done what you did. Especially since I wanted 128GB. Now I am probably going to settle for 64GB or maybe 96GB.
Just went through this today for my daughter- struggled to find an i5 not on pre-order, and the RAM was crippling- ended up going Ryzen 7 for a first time and 2x8Gb DDR5 6000 @ £119 - looking forward to building it with her!
I just got one of the last beelink ser-8s with 64gb for $750. They sold out by the time my order arrived. The newer ones are starting around 830 for a 32gb machine (admittedly with newer everything)
I bought 64GB of DDR5 two weeks ago. That same RAM is now twice the price.
I bought 32GB x 2 of G.SKILL a year ago and paid $204. Now it's $600. Insane
