No disrespect for you yannis I know you love your A10 and that it's great for your light gaming on your HTPC, but if people really need CPU for number crunching or games that are CPU demanding, A-10, Core2, Phenom II, i3 etc simply don't have enough grunt. For example my main game at the moment is Guild Wars 2, even with my i5 2500K at 4.6GHz at times frame rate would drop to 30fps. I tried testing with no overclock, turbo boost disabled and ran the game with two cores (so basically a i3 with HT disabled), and frame rate can drop to as low as below 20fps. BF3 multiplayer is also known to be very CPU demanding as well...and Far Cry 3 is also very CPU dependent (when people got a fast enough graphic card for the CPU to scale with). So you can really generalise that faster CPU make no difference, just because the games you ran on your A-10 is not so CPU demanding.
On a seperate note I just got parts for a Bitfenix Prodigy mini-itx build...I did consider the possibility of A10, but went for the Pentium G2120 instead based on the fact that while Guild Wars 2 "can scale" up to 4 threads, most of the time it doesn't really use more than 2 threads so the G2120 would be faster and consistent performance wise, as well as I got a spare 9800GTX+ (which is tiny bit faster than the A-10's 7660D). CPU gaming performance wise there's no doubt that the A-10's CPU side is no weaker than the Pentium, IF games would use muti-core properly and use all 4 cores fullys...but unfortunately due to sloppy nature of game developers and with them keep shoving games using only 1-3 threads in our face, the Pentium become a more reliable performer, as it wouldn't suffer 25-50% or more of it performance going missing due to games not using 3rd and 4th core...
