Last week we reported some figures from Nvidia that painted a very rosy picture for PC gaming indeed; video game consoles might be winning now, but thanks to the growing popularity of social gaming (CityVille) and digital downloads (Steam), PC gaming revenues are set to enjoy some kind of renaissance. The problem is, those figures came from Nvidia — a company that is definitely PC-centric — and there was a dubious lack of source citations, too.

Well, you can now sleep soundly in the knowledge that PC gaming is making a comeback — and we have an infographic to prove it! Compiled by Ignite Game Technologies, the infographic shows a much clearer image about the impact of casual games and digital downloads on the PC gaming bottom line. Ignite already pegs the PC as being the larger revenue driver — $11.6 billion vs. $8 billion for consoles — and it then goes on a hardware spec rampage that will surely delight PC loyalists… though some of the figures seem a little ostentatious. Did you know that PCs have 1GHz GPUs, compared to the Wii, PS3, and Xbox 360, which only have a few hundred megahertz? (I wish my PC had a one-jiggerhertz GPU…)

Apparently PC gamers spend a lot longer gaming than console users, too — 8 hours, as opposed to 1.4 hours on the Wii, and 4 hours on the PS3 and Xbox 360 (though it doesn’t say whether this is per week or per day). PC games are cheaper than console games, and apparently 44% of all online games played are puzzle/board/game show/trivia/card games. 21% are “action” games (sports, racing, RPG, FPS), and 16% are persistent-world (MMO) games.

Finally, Ignite points out that the biggest-selling PC game in 2010 — StarCraft II — outsold console-favorite NCAA Football ’11 by about 5%. StarCraft II was a special case, though, and I wonder what the next PC game after it was. World of Warcraft? (And shouldn’t that be above SC2’s 700,000 copies?)
