I have been looking to purchasing a laptop, and I found two that have caught my eye, both being Toshiba Satellite S855's. I am on a budget, and these appeared to be the best laptops for my price range.
One has an AMD A10-4600M quad-core with 1 GB AMD Radeon HD 7660G + AMD Radeon HD 7610M Dual Graphics card, while the other has an Intel Core i7-3630QM with a 2 GB GeForce GT 630M graphics card.
I will mainly be using this laptop primarily for gaming, playing mostly Minecraft but also Dead Island and Borderlands 2, but also will be using it for Schoolwork and Photoshop.
Oddly enough, the 7640G is comparable to a 7610m, so X-fire maybe? Anyway, an nVIDIA card will probably run Borderlands 2 better, mainly because of PHYSx.
The first has a better GPU, but weaker processor.
Second has better CPU, but a weaker GPU.
