I would absolutely do everything I could to avoid buying a 7, 1. Last few paragraphs of this article indicate where Apple's high-end desktops are heading:
Apple Inc. is planning a series of new Mac processors for introduction as early as 2021 that are aimed at outperforming Intel Corp.’s fastest.

"For higher-end desktop computers, planned for later in 2021 and a new half-sized Mac Pro planned to launch by 2022, Apple is testing a chip design with as many as 32 high-performance cores.
With today’s Intel systems, Apple’s highest-end laptops offer a maximum of eight cores, a high-end iMac Pro is available with as many as 18 and the priciest Mac Pro desktop features as much as a 28-core system. Though architecturally different, Apple and Intel’s chips rely on the segmentation of workloads into smaller, serialized tasks that several processing cores can work on at once.
Apple engineers are also developing more ambitious graphics processors. Today’s M1 processors are offered with a custom Apple graphics engine that comes in either 7- or 8-core variations. For its future high-end laptops and mid-range desktops, Apple is testing 16-core and 32-core graphics parts.
For later in 2021 or potentially 2022, Apple is working on pricier graphics upgrades with 64 and 128 dedicated cores aimed at its highest-end machines, the people said. Those graphics chips would be several times faster than the current graphics modules Apple uses from Nvidia and AMD in its Intel-powered hardware."
Just get yourself a Mac or PC to get through the next 12 months. Don't spend silly money on a dead end like the 7, 1. That machine is over.
