One of my friends wants to build his first computer, and ive been helping him decide what to buy. Well, it got me thinking, is a dual core cpu still good enough that it will last him at least 1.5-2 years without any performance issues? I see more and more games coming out that put a quad core in the recommended specs(eg. bfbc2, dragon age), and i was wondering if a phenom II x2 555 would do the job(i doubt he wants to take the time to unlock cores). Also, I compared the i3 530 to the phenom 955 on anandtech and it shows the 2 cpus being close to eachother, but the i3 is cheaper, and a dual core. So, would a dual core cpu meet his needs to play games on high/max settings for atleast a year? Or is a quad core the "norm" for new builds?
