Hi Robert,
That depends on what you're after doing.
If you want to improve the Graphics by adding a higher spec'd card then you need to Disable the Onboard Graphics Chip by setting Internal Graphics Mode to Disabled and also setting Init Display First to PEG. Both these settings are made under the heading Advanced BIOS Features.
If you are adding one of the 3 series ATI cards to enable Crossfire then all you need to do is enable Surround View in BIOS and leave the other settings alone.

Hi thanks for the reply i am looking to add an 5450 card and use that as the primary display, so i assume i just follow your 2 points and that's that.

If you're using a 5450 you need to disable the onboard graphics or you won't see the benefit of the higher power of it, if you leave the onboard graphics running.
Also remember to add the extra power lead to the graphics card if it is required.

Hi could you explain this bit some more please ?
Thanks

What absic is saying is that if you don't disable the onboard graphics when you install the discrete card the performance will drop to the lowest common denominator which would be the onboard GPU's performance.
