Can I use this processor without hesitation?

bl

Intel Core i5 540M with

2x 2.53GHz with hyperthreading and intel boost function up to 3.07ghz
integrated HD graphics card with 700mhz

What do I do with the notebook? Youtube, watching movies in hd, office, other surfing and occasionally games like counter striker or Among Us. Nothing fancy.

Should it take a long time?

Ja

Well, in principle, that works with the first gene. The i core are reaching their limits. Even Windows 10 doesn't work as well as you would like it to. I know it would be annoying to work with such a CPU because it often takes longer.

I would get a cheap and used 1050 Ti graphics card. Because it's much better than the built-in graphics.

Then push them into the notebook

Except for demanding games, you can use the lappy for office stuff, but not the fastest, not even with an ssd…
