yea i have to agree w/ roco although im not a computer genius and dont claim to be, i can tell u i currently have a single core processer a Intel Celeron 2.4ghz w/ 1 gig memory, and my wife can have like 6 facebook pages open at one, and their filled with alot of pictues.....and it seems to work fine, so i cant imagine a dual core, just doesnt make sence....id format my hard drive and maybe invest in some more memory, just my 2 cents......just a thought
