I have had my 5000 for about 9 months and I am still fascinated with it's versatility and capability. This is the best ham equipment I have ever been lucky enough to own. I run CW much of the time and it works fine with the delay set at 200ms, a personal preference. It works for me with delay in the 50ms range, probably lower but not important to me.
My HP Pavilion (2008) needed some work to reduce DPC's but easy and has been very stable and I added an SSD to boot faster. Also the computer is dedicated to the 5000 without games or other nonsense.
So, the 5000 station works great. No issues and will be here until I can manage a 6xxx.
No one should discount the capability of the 5000. Yes, it's legacy, PSDR is mature, but for the money on the used market it can't be beat in my opinion.
