To paraphrase Ann:
With that i7-920 and only 6 GB total of RAM, Premiere Pro 2020 will launch; however, there will be major stability issues unless you upgrade to newer hardware witrh more RAM. The program will crash if you try to do anything significant within that program.
And I am assuming that that i7-920 was running Windows 10. In that case, then FCP will not run at all as it is OSX only. Windows cannot run Mac-specific programs at all. (And I cannot say anything about "Hackintosh" as weird issues can, and do, occur in those systems.)
