As you can CLEARLY read, the results are for a very high resolution. I won't be going higher than 720p or 600p.
And? Higher resolutions stress the GPU. CPU usage is relatively indifferent to resolution (as I understand it). Although, some graphical effects in some games may take more CPU to enable them.
Edit: Again, "slideshow".
But hey, if you feel you can get enjoyment out of a game, on a C2D and a 5450, be my guest. As they say, "ignorance is bliss".
I just remember trying to play WoW on a GeForce 6100/6150/6150SE IGP, with a single-core AMD64 CPU, and it ... wasn't that much fun. I think I had minimums of like 7-9FPS, and maximums of 18FPS, at a low resolution.
That's the type of gameplay experience that you are looking at, with modern games and your rig.
Edit: This was before the expansions, WoW was known to run on almost anything, and it wasn't very graphically-demanding back then. Supposedly. I suppose that it was amazing I could even "play" it on an IGP.
