No social gaming
That's not entirely true. It's easy enough to have social gaming from anywhere from 2 people up to 500+ people. In GW2, for example, one guild has a WvWvW vent server with 200+ capacity (usually full) another with a Ventrilo server with 150+ capacity (also usually full).
If you game with friends then there's all sorts of options. Some free others not. Skype, Mumble, Ventrilo, Teamspeak, etc.
One key factor that is often overlooked is that building a PC yourself is a lot more expensive if you have to also buy the OS...
Not really, I just posted an example a few pages back of a system that exceeds console gaming quality levels for only 375-425 USD including OS. And if you shop around you can get it for cheaper than that. Possibly 300 USD or less.
While slightly more, it certainly isn't "a lot more expensive."
That also includes Mini-ITX such that the form factor approaches that of a console. Will easily fit in a backpack or under your arm if you want to take it to a friend's house. Will also easily fit into a home entertainment center as the case was designed for HTPC duties.
That price above could also be lowered quite a bit if you don't mind sacrificing some quality to be on par with consoles in graphics quality.
There IS a price, however. You have to build it yourself. In this day and age it's extremely simple, but some will be intimidated by having to do that. So a pre-built system will obviously be more expensive depending on the shop you go to. But it may not be "that" much more expensive if it's a large shop that can buy parts in volume.
And once you do that, you also end up with a Home multimedia center that puts both the X360 and PS3 to shame. Full unrestricted web browsing. Unrestricted media playback capabilities, etc.
For just a little bit more, you end up with a far more capable media center and gaming portal. You do lose access to system exclusives, but you do that if you buy a PS3 or X360 anyway.
It certainly isn't for everyone, but you "can" game with PC for comparable cost to consoles short term (lower cost long term) if you're willing to put some work (an hour or two) upfront to order the parts and build the system. Which obviously isn't for everyone. But again, the cost is similar for a similar or better experience.
