I built a ROG Zephyrus equivalent: The ROG is $2,100 and the Framework is $2700.
So its more expensive but not $1500 vs $4000 expensive.
This was comparing the lowest end model ROG because that's the only one with a 5070. It was also 100% like-for-like, such as paying for windows, something I personally wouldn't do with a framework.
Buy the core parts from Framework and then buy & install things like NVMe and memory yourself. Will save a considerable amount.
Aye that's not a bad plan, to be honest I think my Strix still has a few years left at least but we'll see.
Storage is expensive at framework. I bought the storage for my 16 elsewhere and it was substantially cheaper.
My ASUS ROG Strix cost me $1500 back when the 3080's were new and has a 3080. Have prices risen that much?
