Seriously, the power of i7 is pretty much unlimited when you are planning to run high quality graphics on a normal screen but can it do the job of a great GPU (PShader 5 with a decent clock speed) just with its spare processing power?
Can it carry out, say, a 3D video game on its own on a 19" screen?
