"How much money do you spend on Gaming System?"
This question could really be clarified. All total systems used for gaming, as well (hey, nethack is a game, and my laptop can run it!

)? FI, here's my situation:
I made my main desktop without gaming in mind. Later, I added a nice video card.
Since the first ~$1300 was with no gaming in mind (and wasn't spent all at once), how does that play in to the cost? If I had bought it all new at the time I added a nice video card, the total cost would have been well under $1000, as well. PCs can make this simple question ambiguous.
Graphics quality and 3D capability are basically one in the same. All hail digital video ICs.

Here are a plethora of examples of what one might put in a living room:

Finally, on the importance/ordering bit, wouldn't be valuable to game catalog size as an option to prioritize?
