I would go for AMD Fusion, atleast an A8 3500m (native quad CPU with DX 11 GPU). Its better then the i 3.
The CPU core of the AMD A4/A6/A8 APU is based off of the Athlon II CPU. Therefore, clock for clock it is slower than a Phenom II CPU which is slower than an Intel Core CPU.
The graphics core in the AMD A4/A6/A8 APU has better performance than the Intel HD 3000 graphics core. But the poster didn't say anything about playing games.
