Hey there, @Vala!
It would be really helpful if you share your PC specs and more specifically the motherboard model. Upgrading to a solid-state drive is great, and you will see things get a lot snappier than before. So you will definitely experience much faster booting times and overall performance boost of your system. If your mobo incorporates SATA III ( 6 Gb/s) ports, you will definitely notice the difference as these ports allow the SSD to communicate much faster when the read/write speeds could reach ~ 550 MB/s.
Even if your motherboard doesn't feature SATA III ports and instead you have only SATA II ones ( 3 Gb/s), you will still notice the performance boost, even though these ports bottleneck the capabilities of the solid-state drive and limit the transfer speed (read/write) to around ~ 300 MB/s. However, I think it's still worth it.
In the Tom's Hardware website, you can find some
great articles and benchmark reviews of SSDs.
Hope it helps. Good luck & let me know if you have more questions!
