We don't know what future games will be, but the i3 is a good gaming CPU that can be had for a low price. The i3 is a dualcore however it has Hyper-Threading which means each core acts like two so the i3 has 4 threads like a quad-core. Otherwise, more expensive processors such as the i5-3350P/3570K are better. Also important in gaming is the graphics card.
