You have an i3 there and I have a couple ancient laptops that one is great on youtube and more and the older one works but not full screen on videos.
You have picked a far better model than my old 2009 Sony Vaio with Core2Duo and it's 4GB RAM. This one is good enough to put 1080p up on the HDTV.
And it's far better than my son's returned to me Dell Inspiron e1505 (2006 model) CoreDuo, 2GB model. It has a cheap 120GB SSD or it would be gone. It does the audio things well but full screen it just can't handle it.
You're fine.
i was looking at this laptop from dell http://www.dell.com/us/p/inspiron-15-5559-laptop/pd?oc=dncwv2370s&model_id=inspiron-15-5559-laptop and was trying to confirm if the i3 is good enough for my pc needs which is just the basics of web browsing, youtube, itunes/spotify, forums, etc. ...no gaming or heavy workloads. i would not need the i5/i7 for just those basics, correct?
