Looking at the ones on this site? Windows will be included. The 7970m is considerably better than the 675m. Be aware that the 4600m is quite a bit slower than mid range i5 CPUs and more so for the i7, but it is a lot cheaper. Also, the 4600m has been superseded by the 5750m, which is some ~20% faster overall iirc, cooler running and uses less power at idle
