The technicals on the laptop are pretty irrelevant for playing poker, but the main thing you probably want and need is
(a) a good GPU (Graphics Processing Unit, otherwise known as a video card)
(b) an HDMI output
The problem with laptops is the screen size is always tiny, which means you can't play many tables without it being a real struggle.
So the best solution to this is to connect your laptop up to a big-screen HDTV (or a larger computer monitor) which will have a LOT more screen real estate for multiple poker tables.
That's where the HDMI output becomes essential, so you can make the connection to the television screen. And a good graphics card is also necessary for this.
That's my biggest tip. When I play on my laptop screen, I only play one table because even two tables makes them very tiny and hard to see unless I stack them (which I don't like to do, I always tile my tables).
What I love about the laptop is that it gives me portability to walk around or sit outside, but if I really want to grind I have to use the HDMI cable and now I don't have the portability anymore. So this solution is a bit of a trade-off and I often just use the laptop screen and just play one table only. If I play multiple tables I usually just use my desktop PC which has the much bigger monitor and much better keyboard and mouse.
