Summary: Why having and paying for integrated GPU when you have graphic card ? I prefer 2mb of l3 cache and more instructions supported by this CPU. Also even it doesn't support hyperthreading, I don't feel there is 'lost' there. It's a work horse, I recommand it.
Pros: Goes like big i5 for cheaper. Deliver honest and excellent performances. Multitasking is a charm, decent temperature and 'low' electricity consumption for performance it gives. I like it much over my last i3 4330. Cpu isn't the choking point anymore in my system. I play and work somewhat hard with my computer and everyting is going fine.
Summary: Good processor: fast enough for the NAS I've just assembled, relatively inexpensive and fast, and supports ECC so the system overall becomes very robust ( a must for a storage server). My only peeve is that it doesn't support SMT (aka Hyperthreading), so it can only process 4 threads simultaneously instead of 8... but it's not a problem for my use case.
Summary: I doubt I'll notice the difference with HT and not but it's always nice to have especially as I learn new things to do with my server. Regardless this cpu does everything I expected it to do perfectly.
Pros: Runs cool. Great performance. In a small home server that hosts games and media.
Cons: I didn't realize this didn't have hyper threading. Completely my fault so I'm not deducting an egg. However considering the 1230 is only $30 more with HT and faster base clock the 1220 is pretty over priced.
Pros: doing great in a NAS4Free box on an ASUS P9D-V. Writing to disks with compression on the fly at max throughput the utilization is still only 20%. The box heatsink/fan are an improvement over the intel of years past.
Summary: Paired this with a SuperMicro X10SAT to power my new FreeNas box and so far it's performing like a champ (and lightning fast). However I made the mistake of not checking beforehand, and this cpu does not support integrated graphics (n00b tip: for xeons, integrated graphics support is denoted by the model # ending in a 5, so while this E3-1220 doesn't support integrated graphics, the E3-1225 does).
