This was in my first pc, still have it

Posted by: N-

The first pc i got had this cpu in it, mainly used it to browse the web (on dial up) and to play some games like CS. One thing i remmber about this cpu, or at least mine anyway, was that it would heat up alot even when idleing, had to bolt a 80mm fan to the HS.
