First of all, good video quality depends most importantly on the quality of the video itself.
As for the viewer, some of the factors to look out for are:
- good screen resolution (1366X768, 1920X1080 or better)
- good screen size (14', 15' or bigger)
- internet download speed (2-3mb+)
- good graphic card (NVIDIA, ATI or Intel HD graphic cards with 256MB+ GDDR3)
As for the processor (CPU) or memory (same as RAM), it's not as important. The better the better.

The most important thing to look at when buying a laptop is the random access memory, random output memory and the capability and type of the processor.
Memory is the key essential to tuning and upgrading a laptop to make the processor faster. BestBuy, Target, Fry's, and Wal-Mart are some stores you can purchase additional memory at.
Only some parts are upgradable. The memory usually will be, and the processor can be upgraded but will take an experienced technician.
A gamer laptop would need to have at least a dual core processor and extra memory. Many laptops will state in their description if they are for gamers or just the average laptop.
Your question is not very clear but do you mean "what determines the speed of a laptop?" Well the speed of a laptop varies just like a desktop depending mostly on the processor and how much RAM (random access memory) it has.
The Type of transfers that must a computer interconnection structure support thats a bus is the following: (1) Memory to Processor (2) Processor to Memory (3) I/O to Processor (4) Processor to I/O (5) I/O to or from Memory
processor and main memory
Both the processor, which allows the computer to do tasks, the better that is, the faster your computer can work the RAM which stores the things for the processor to process, the more you have the better. AND the hard drive, the faster this is, the faster the processor can grab information off it.
The memory unit's size that depends on the processor is the bit.
