With Black Friday / Cyber Monday just a few weeks away you want to be keeping your eye out for extra nice bargains.
Basically, you want at least a fast dual core CPU, Core i5-2410M or better.
And the best GPU/graphics card you can fit into your budget. Hopefully, GT 540M or better.
Are all of these laptops good in quality? won't overheat, decent looking visuals etc
The brands are all good - I don't know about the specific models. Most laptops won't overheat unless you do something odd to them (try and overclock, run them in a high dust env for a long time without clean, run them in 120 degree heat, etc).
And they all have better video cards than the toshiba.
