I'm looking for a midrange graphics card, preferably Nvidea because they are the most common, for around £100/$150. I'm looking for a multimedia laptop around £700/$1000 and I need a decent GPU to handle SOME games like SRTT and SimCity with ease on medium/high settings. I just need to know what GPU to look for so I choose the right laptop. A selection or category would be helpful (e.g. GTX...etc) Many thanks!
