It's old, but it runs fine, i don't play some games that require much CPU usage, like TS2. It runs on 50/60fps on medium settings. GTA SA runs around 40/50fps (low settings) So if you have an i3-2100 (and no graphics card like me) play games around 2004-2009! But yeah, it's great!

As i can see, you just made i3 only with 2 cores, but it's 4 cores :\
