Minimum 8 gig RAM (Random access memory)
Minimum i5 processor (engine)
Minimum 500 gig hard drive (Storage)
Most laptops are similar, just get one you like the look and feel of with a good price
These specs as a minimum will future proof you for a quite a while.
Altenatively if you only surf, shop and social media etc, consider a chromebook. They require no software updates, no virus protection which is a great on going saving, it is all done for you automatically
I have two chromebooks in the house and a windows desktop.
Desktop is only used for video and music editing, everything else is cromebook.
Chromebook only has a small hard disk so stores everything on the cloud which is good as you can access it anywhere as long as you have internet access.
If you insist on having microsoft office then it is a windows based computer for you.
Chrome book uses "sheets" and "Docs" instead which are very similar to Excel and Word.
I bought my mother a chromebook after a windows PC I bought her, she loves the simplicity of it and would never go back.
And just to mix it up my daughter has a mid range surface pro (windows) which she is very happy with.
You can also easily edit photographs with google Pixlr Express on chromebook.
Any good store will be able to guide you, and yes you can play many types of poker on a chromebook.
I use my chromebook 99% of the time
Hope this helps.
