My motherboard is gigabyte g41mt-s2 rev 1.3 . I'm currently running intel core 2 duo e7500 2.93 ghz . I want to know whether i can use i5 or i3 with that same motherboard . Core 2 duo is a 45nm cpu . So my motherboard specs tell that it supports 45nm intel multicore processors , so can i use a i5 which is a 45nm cpu . And my motherboard says gt support core 2 duo , core 2 quad , core 2 extreme too . As i am new to this cpu thing i would use some answers . Plz .
