I was looking at Cheap CPUs and I noticed the Intel Core i3-3225 3.3GHz. It's $144.99 on Newegg.com
It's the only i3 that has Intel HD Graphics 4000, which makes it kind of an oddball. All the other i3 chips have Intel HD Graphics 2000/2500/3000.
It's an IvyBridge part. It's only a dual core, but it supports hyperthreading, so it's like a ghetto quad core. It supports DDR3-1333/1600 memory. It's a 55W part (lower power means less less cooling needed).
