For the performance, it’s actually quite reasonable. 4070-like GPU performance, 128gb of memory, and basically the newest Ryzen CPU performance, plus a case, power supply, and fan, will run you about the same price as buying a 4070, case, fan, power supply, and CPU of similar performance. Except you’ll actually get a faster CPU with the Framework one, and you’ll also get more memory that’s accessible by the GPU (up to the full 128gb minus whatever the CPU is currently using)
