What Windows operating system are you currently running? Adobe Premiere Pro CS 5.5 was for Windows Windows Vista and Windows 7, and did not need a very powerful machine.
Are you inquiring specifically about Video Pro X 13 as the processing requirements are much higher than your previously stated editor.
None of the current programs are being sold as marked ready for Win 11 yet so Win 10 is the best operating system to have for Magix products.
The first thing you should do is check if your computer system is powerful enough to run any of the programs before even considering purchase or you may find the programs either don't run at all or do not run well.

What types of files are you hoping to edit. Are they from a camera or created from something like a screen grabber or from VHS tape? The more detail about resolutions and frame rate you can give, the better.
