Hi! First of all i must admit to being slightly clueless on laptops and what makes a good/poor laptop.

However, i am looking for a new laptop to be able to use multiple programs at once and play some fairly low graphically taxing games (eg Football Manager). I have decided i would like a quad-core processor, a RAM of 4gb or more and a hard drive of 500gb or more on a budget of £450 or below. However i have read that i need a decent graphics card to play graphics on the games.

I have narrowed my options for laptops down to 3, with one offering a 512mb dedicated graphics card, another offering an AMD radeon HD 4250m (up to 1.87) integrated card and i am unable to find the card used on the 3rd (I will provide a link below if anyone is able to find it for me). So basically my quetion is, which is better for the type of gaming i want to carry out, a 512mb dedicated card or a 1.87gb integrated card?

My 3 options are on the links provided below. Which laptop should i go for?
