Taip, taip.. t.y. uzteks ir Pentium'o.. ir taip, i3 geriau nei Pentium ir atitinkamai brangiau.

i3 = Pentium G4400 + HyperThreading + galingesne integruota videlka (bet jei geimint - ji nepakankama ir pas i3).
Pentium G4500 = i3 be HyperThreading (t.y. su tokia pacia intergruota vis vien nepakankama videlka kaip pas i3).
