HW PS3

[Fullesh]

Tak mi hlavou poslednej dobe melie, ze z akeho HW sa sklada tato konzola a tez XBox360. Su to komponenty podobne k PC, alebo je to uplne nieco ine. Rad by som sa dozvedel zopar info o otmto. Kedze kamos furt vyprava ze tam su 4 naj. grafiky, 4 naj. procesory a ramky. co sa mi zda nemozne. Mohli by ste mi to objasnit ?
