Ok I want to do a cheap build for everyday use and playing some old games. The two processors I was looking at Pentium G620 and the Celeron G550. Both are based on the Sandy Bridges architecture, both are dual core, both are clocked the same but the Celeron is alot cheaper. So what's the difference? If the performance is the same it would seem pointless to spend 13 dollars more on the Pentium.
