That video card is pretty weak. The 5700 was okay, but an LE is a crippled version of it. Could it be a little low? Sure, however, I'd be more concerned with low performance in an actual game. There are NO games based on the 3DMark engine. It's sole usefulness comes in when they are able to test features no game in the market can. Even then, it's very fickle. It's not a 'realistic' benchmark because it's simply not based on any tangible game. That combined with some pompous threats to [H]ard|OCP (even factoring in that the owner can be an ass) for criticizing the usefulness of 3DMark, we have removed and will not use 3DMark in our reviews.

Having said that, 3DMark is sensetive to things like if you've installed your chipset drivers or not. Other games may perform better with the chipset drivers installed (and tends to be recommended that you do so anyway), but 3DMark is picky about this as well.

If you want better gaming performance, upgrade your video card. Also make sure you're comparing similarly equipped systems, particularly with the same video card and CPU, followed by the RAM.
