In essence the concept of Dual graphics from AMD was pretty but it's real world implementation was far from it. Lack of drivers and developers supporting it on their platforms meant that it's best achievement was a 10% increment(at best) but not something as envisioned to be a 50% scaling.
To add more woe, the APU's were designed to bridge the gap with entry level web gaming to the masses on a mobility level. In truth they were just hot headed processors with a bundled iGPU which wasn't capable of driving eye candy.
Now do you intend to game off the aforementioned Toshiba laptop? If so then what sort of titles do you want to game on? If this doesn't turn out to be a good option, what other options do you have at your disposal?
so it seems a8 is not a good idea
i wont be playing AAA titles (maybe some on medium graphics) ,i have just started my hunt for laptop and this laptop seemed quite appealing to me ,i'll be looking for laptops in same price bracket (200-300$ in my country for used laptop, im not buying new) whats a good intel + nvidia combo laptop u can recommend in my price reach just make sure laptop is not more than 4 or 5 years old
