Right, but that’s top of the line stuff. You can easily build a PC with a 70 tier GPU for less than $1500 and you’ll still have a kickass gaming PC.
The XX70 tier equivalent mountain bikes cost like $3000-$3500. I’m thinking along the lines of a Trek Remedy 7 (which is what I have), a base Santa Cruz Bronson, or a base Specialized Stumpjumper. There are plenty more but those are just 3 from some big brands.
