Improving Graphics Performance in Intel Motherboards with External PCI Express Graphics Card
There is a problem faced by some users, who have bought new Core i5 or core i7 processors, and using Intel motherboards. This third or fourth generation Intel Core Processors, have inbuilt GPU in them. If you have a graphics card installed, then sometimes it may not work, because all your Graphics Processing is being done by the onboard GPU on the processor, which results in lags in games, and low FPS. On the Intel H77 motherboards, and other new motherboards, there is a BIOS setting with which you can disable the Graphics Processing Unit (GPU) of the CPU, and use your PCI Express Nvidia or AMD/ATI graphics card for all graphics processing task. I noticed this when my friend bought a new Intel third generation core i5 processor, along with an Intel motherboard. The Windows Experience Index ratings decreased from 5.0 to 4.9. He was using the same Nvidia 9500GT graphics card he was using earlier, but after installing the new motherboard and processor, the performance decreased.
So here's how you can make your PCIe graphic card, as your main GPU, and disable your onboard GPU on the CPU:
1)Start your computer, and enter the BIOS. Press F2 on your keyboard as soon as you seen the screen with the Intel logo.

2)Now you have entered the BIOS, go the advanced tab by pressing the right arrow button on the keyboard.
| BIOS Main Screen |
| Advanced tab BIOS |
3)Now select "Video Configuration" as seen above and press enter. Now select "Primary Video Adaptor", press enter, and select "External PCIe Graphics (PEG)".

4)Thats it. Now go the EXIT tab, its the last tab. Select "Exit Saving Changes", and exit.

Now restart your comuter, and you must notice a difference in playing games, and other tasks such as seeing HD movies, and other graphics intensive tasks. When I performed the above steps, in my friend's computer, the Windows Experience Index increased from 4.3 to 5.0.
I tried this on Intel motherboards, there must be similar process for other motherboards also.
