Actually, I prefer "Value PC", but the "gaming pc" name has been around a while for the cheap Tom's builds and initially was not my choice to go with considering the test suite and all. Still, it does fit though as we do strive to build a top gamer for the budget. But it still needs to show up for the other tests; games are obviously not the only consideration for the SBM's, regardless of the system name.
LOL, believe me, I do play games and don't value synthetics much myself either. Unfortunately, these SBM's rob my play time though. Luckily with a day off, I logged a good number of hours into Fallout 3 today.
To be honest, performance testing games is my favorite part of all hardware testing. Shoot, that's the main reason I wrote the A64 gaming article a few months ago that highlighted just how well the X2's can still do.

And I'm value oriented, so no arguments from me claiming that a cheap PC can't game. I'm no stranger to playing on AX2 rigs either and have a couple of them in gaming rigs on my home LAN. "Running Perfectly" is a huge stretch though if you broaden the scope of games you play and want to play max details including CPU related settings. The minimum fps affects smooth gameplay and is far lower on a CPU like that. I think you would be surprised how much better your gameplay could be with a decent clocked C2D vs that X2 5000+. But, I'm glad it keeps you happy and I totally agree with you the GPU is more often than not far more important, just as long as you have enough CPU. Also, I consider your 19x10 to be a high resolution where of of course your GPU can shine (and was a good choice). Still, your kidding yourself if you think the overall level of gameplay (in ALL games) is even close to what it could be with a high clocked C2D CPU. Do you overclock the 5000+? If so, you know the CPU is quite important. Crysis I saw a huge benefit in actual gaming FPS overclocking my Q6600 over 3.0GHz(paired with SLI 8800GT).
And as far as your challenge ... I've had something in the works and if it pans out... you may enjoy seeing it. (Fingers crossed)
Happy New Year Marveaux; All the best back at ya.
