Low memory/video performance

I have a vanilla Macbook Pro (Mid-2007) which I just recently bought. I benchmarked it under windows, using pcpitstop.com and it told me I had low memory and video card perfomance.

I wouldn't worry about it if it was something like 90% compared to a similarly stocked laptop, but it says I'm getting 45% video perfomance, and 41% memory performance!

I remember getting similar results with geekbench under OS X.

If anyone can give me any suggestions/point me to any guides/tell me it's a bug on their part and they're lying to me, it would be greatly appreciated!
