Okay, good, I don't think most people get Xeons because of that, or because they're meant for server farms.
Xeons can be used in gaming and streaming rigs and are often great options for that. People who game are not usually going to run integrated graphics anyway. The Xeon is much cheaper than an I7 and is just about as good, minus the overclocking capabilities.
Many intel cpus come without intergrated graphics,the reason for this is the need for lower tdp as most of those cpu are multicore xeons-core i7 who have already high tdp and their use is absolutely professional and the need for graphics is not big and so igpu would be a unnecessary add in the hole cpu thermal configuration.
