Most people can't build a gaming computer though.
I don't understand this. Building a computer involves:
1. Asking the guy at your computer part store if the various pieces you're looking at will mesh (he will know). If they don't, he will offer you alternatives
2. Putting your new (or re-used) tower on the counter
3. Open the box with the motherboard, open the manual and follow the pretty pictures
4. Open the CPU box, open the manual and follow the pretty pictures
5. Open everything else except the PSU and install them in any order, following the pretty pictures
6. Install the PSU following the slightly harder pretty pictures
7. Close the side of the tower, plug in the monitor
8. Plug in, turn on
9. Insert Windows 7 disk, install
10. YAY
Your other points about having to wait and buy on sale? That's not hard, and is actually generally good financial sense in day-to-day life. Just get one game you really, really like and buy the good deals as they come, and you'll have a major backlog by the time you're done with the first game. And you'll have bought 15 PC games (or more) for the price of 5 console games.
