Which should I buy? A brand new Pentium G2020 or a used i3-2100/2120 which costs about $10-15 more? I encode from time to time but my main concern is the igpu as I only use the onboard and it's more than sufficient for playing a lot of the older games. Is there a big difference in the graphics between the two? Btw that would be replacing the Celeron G530 I currently have. It's awesome in everything I use it for, even in multitasking, but takes up a lot of time on encoding. Thoughts?
