The onboard gcard is dragging down the performance of the discrete card.

It is to be expected. SLI basically boils down to this. One card processes half of the frame (screen). The other card does the other half of the frame.

These 2 half frames are then synchronised and displayed.

Here you have 1 fast card, 1 slow card.

The fast card finishes its half of the frame and waits for the other card to finish its half. You are limited to 2x the speed of the slowest card.

In this case your discreet card is more than 2x as fast as the slower card. So using the SLI is not worth it. If you had bought an 8200 discrete you would have possibly doubled the performance of the integrated card.

To be honest these hybrid SLI rigs can be useful for older games on the cheap, but if you are looking to play crysis you simply can't really use an integrated card.
