My laptop has a T7100 @ 1.8 GHz (yes, it's a mobile processor) had a score of 4.7. I doubt that the E6300 would have a lower score than the T7100, since the E6300 has a 1066 MHz FSB while the T7100 only has an 800 MHz FSB.
I can tell because in Vista the max score was a 5.9 and my old HD2900Pro 1GB would always stay at 5.6 no matter how far I overclocked it, yet you are running a 6.4 for graphics. In Windows 7 I think the max it 6.9 or 7.0 and my Q6600 that used to be maxed at 5.9 running 3GHz is now lower.
I think what happened is that in the Windows 7 WEI, they updated it to match the current CPU tech such as Core i7 and Phenom II. So since you have a dual core and quad is more common, the actual CPU score will be lower than it was in Vista, which I would assume your husband had it in because a slight overclock to 2.11GHz would not warrant doubling the WEI score.
As for gracefully, if you are running Vista and not Windows 7 that would be why your CPU got a higher WEI score than the OPs. At the time, the hardware that Vista had for maxing out was 65nm Intel quads so the 65nm dual cores (both the E6300 and T67100 are 65nm Core 2 based dual cores). Now they have Core i7, Phenom II and soon 6 core CPUs.
the score in windows 7 is between 1 and 7.9. I got 7.4 on my CPU and its running at 3.2GHz
the only way to get 7.9 is when you overclock the new i7's to 4GHz.
so a score of 2.6 for a 1.8GHz processor seems about right.
I have a Dell Inspiron 9400, t7200 cpu, all my numbers were ok(in the 4-5.0 range) except my CPU which was 2.6, and I tried everything to get it up. I was beginning to think my processor was damaged but the Intel diagnostics said it was fine. But the other day I bought a new battery to replace my failing one and decided to re-run the WEI test, thinking just maybe. It went from a base score of 2.6 to a 5.0 by simply replacing my battery.
Give it a try. Nothing else I read on forums helped me.
