First up Userbenchmark is only a very fleeting, vauge, semi-possible idea of how your PC might be running. Better is something like 3dMark, which while more for GPU's it also gives a better idea of where your CPU stands.
Is your GPU OC'ed, many of those you compared with probably are so will get a higher score, the ssd may be running a windows app or even several in the background during the test so it scores slow. How much data is on it, how often it has re-written etc.... ssd's do lose performance with age and use (don't we all)
Important is how it is running doing what YOU want it to do and helping you in quality work and leisure time.
If you want please post your full system specs and more help can be given if required. Very important.... age, make and model of your PSU!!
Cheers
