You get a 15.6″ Acer Aspire 5560G (5560G-7809) gaming laptop for less then 410$ = top performance for 410$ and even for 450$.
1. AMD Quad A6-3420M CPU
2. AMD Radeon HD 7670M GPU (which is, again, a rebadged Radeon 6650M GPU) and in many cases very close in performance to its big brother, the 6750M.
3. 4GB DDR3 memory
4. 320GB HDD – not great, but OK.
