You get a 15.6″ Acer Aspire 5560G (5560G-7809) gaming laptop for less then 400$ = top performance for 400$ and even for 450$.
1. AMD Quad A6-3420M CPU
2. AMD Radeon HD 7670M GPU (which is, again, a rebadged Radeon 6650M GPU).
3. 4GB DDR3 memory
4. 320GB HDD – not great, but OK.
This is an instant rebate so you don’t have to suffer.
