Will I be able to update this I9300 to >4.4?

I'm new in Android world, and I have to buy cheapest Android phone that will be able to handle Android 4.4 or newer.
I have found that the best option is Galaxy S3 and that there's one on Aliexpress. I'm aware that it might be a clone but it will not be my primary phone. It just has to be able to handle newer Android.

Can't post a link, search for the top ordered Samsung Galaxy S3 I9300 on Aliexpress.

Has anyone tried it? Will software see it as genuin S3? Thank you!
