Hello,
I wanted a bit better graphics performance on my computer to get better FPS in games etc, so I got a Nvidia GeForce GT 430, which is not really good but its not bad either, and I already have a integrated graphics card inside my motherboard (AMD Radeon HD 8370D).
So I added the Nvidia graphics card inside my computer and it worked fine, but then I realized that it is not using the AMD Radeon HD 8370D anymore, which is actually a lot better than the Nvidia one, so I got like 50 fps when I usually got 120 for an example, so I went to the bios and checked if I can do anything to fix that, but all i got was something like this :

Graphics card usage - Auto (Which was selected and that disabled the integrated graphics card)
- Force Integrated Graphics Card (Which I selected because I dont want my performance to be bad)

And I also tried if the other graphics card is working, so I got 2 monitors now, one connected to the MB IGPU and the other to the Nvidia GPU and they both work.
Also I checked the Nvidia control panel and it says GT 430 is there, (so that means that it works)
but it doesnt say or show anything about the AMD graphics card, nor do I have a SLI option.

Same with the AMD Catalyst Control Center, there it says the AMD Graphics card is there but that aswell doesnt show or say the Nvidia one.
PS: I ALREADY INSTALLED ALL THE LATEST DRIVERS! So please don't suggest that :) 

So anyone got an idea how can I use both of the graphics cards at the same time so I could get better performance OR If i even CAN use them? Because one is Nvidia and the other is AMD and one is a dedicated and the other is a integrated one.. Please help!

My rig:
- AMD A4-6300 3.70 Ghz with AMD Radeon HD 8370D graphics
- Nvidia GeForce GT 430 (the one I recently added)
- 6 GB ram
- 2 TB HDD
- Gigabyte GA F2A55M-S1 Motherboard

I hate to break it to you, but you can't use and AMD/ATI graphics card in combination with an Nvidia graphics card. You can continue using 2 monitors though.

Oh man thats sad, means that I have to change my motherboard and probably my cpu too if I want to use 2 graphics cards then :( 
Unless something else works with my setup like a amd graphics card?

yeah, you can't. and besides, i don't think a 430 can go SLI. just a tip, don't buy anything lower than a x50 (450, 550, 650, etc). Go higher if you can.
you don't have to go 2 cards, buy 1 good card, it would be enough. of course, 2 cards is an option

You are correct in assuming you will need to change your motherboard. Your board only has 1 pci slot for a video card. Your best option is going to be to use a single graphics card instead of trying to do 2 unless you do a complete system rebuild from the ground up.
