I have 325 in my VGChartz collection so far.
It's pretty accurate on the console part. Although it's missing Boulder Dash EX on GBA (no artbox and I apparently I don't have enough post to add it) and my old VIDEOPAC games (Odyssey² in North America). It's also missing my two Game&Watch (Donkey Kong II, Mickey & Donald)
For computers, my PC collection may have 3 or 4 illegal games max. And I'm pretty sure it's missing quite a few games. I also had an Amstrad CPC before that, with a lot of games (a lot of illegal ones though).
I'm buying a lot of games lately (both current : wii, DS, PC and older : GBA, PS, PS2, PC,...), more than what I have time to play. So my backlog is starting to get a little too big. I don't have a lot of new current games planned for the summer, so hopefully I can work on reducing it a bit.
I don't even own a PS3 or a 360, so I'm not even a "hardcore gamer" 
. I can't imagine the collections those "hardcore gamers" must have (I guess they all look like Konnichiwa's 
).
