I know that the M versions are built for laptops but let's make this as an example:
Laptop has: i7 - 4GB RAM - GTX580 (3gb dedicated)
Desktop has: i7 - 4gb RAM - GTX580M (3gb dedicated)
If i run a game like GTA IV, will there be performance differences between the laptop and the desktop having them at the same specs at everything except the graphics card version?
Like how the graphics look, the anti aliasing quality, and the FPS?
