I do prefer the i5 over the i3 and if you follow tomshardware.com you may realize that some may love or hate AMD or nvidia but at the end of the day both do the job.
Given no indication of use, I'd choose by price.
By reading many reviews about notebooks I came to the conclusion that the best models come from HP, but they are of course more expensive, while Toshiba provides cheaper notebooks, but with great quality also.
I have selected a few models from both HP and Toshiba, they all have Intel Core i3 or i5 cpus, and my requirements are 4GB of ram, usb 3.0, bluetooth 3.0, wifi b/g/n, but I was not sure is it better to choose an i5 with Intel graphics, or an i3 with AMD or nVidia graphics? Gaming is of course out of question, it's intended for work only.
<div>Here are my chosen models, any advice to choose between them, or even some other models if you think.
TOSHIBA Satellite L750-1MX
TOSHIBA Satellite L750-1MW
TOSHIBA Satellite L750-1Q0
HP ProBook 4530s LW841EA
HP ProBook 4530s A1F79ES
</div>They are very similar models and very close in prices.
Thanks for any opinion
