Programming Light video/graphics editing Sim racing (iRacing, rFactor mainly) Does anyone have any numbers on these? e.g. framerates 4(+, ideally) year lifespan Note: I have a 24" monitor, so real estate isn't really an issue. I am slightly worried that the i7 8gb model will be underpowered and will not stand the test of time as well as a pro. I was hoping you guys could provide some insight, as I haven't bought a computer in some time and am a first-time mac-user. Thanks!
