How to avoid conflict between APU and a Discrete Graphics Card?

I recently upgraded my PC with a GTX 750 by Nvidia and notice some driver issues and performance drops in games. I assumed this card would be great but in games there is a noticeable stutter and drop in frame rate.

Games are able to run, but would stutter from time to time especially during in-game combat. Some games like resident evil, the running animation would seem choppy. My fps would be in the low and mid 20's even with low settings.

I uninstalled the amd catalyst suite and old video drivers and did a fresh clean install of nvidia's drivers but still seem to have that same issue. I'm using an hdtv running at a resolution of 1600x900 with details turned down to medium and low settings.

I mostly play mmorpg, indie games, and resident evil. I'm connected via hdmi using an adapter to convert it to mini hdmi, reason being that my graphic's card only supports mini hdmi, vga, and dvi (hdtv only has hdmi).

The Brand of my motherboard is MSI (model no. a78m-e45 v2) and my graphics card (PNY). When I run benchmarks it doesn't seem to recognize my cpu which is an a8-7670k (kavari). My system is all running at stock speeds.

I am wondering if there are any conflicts with drivers that may require a fresh install (reinstalling windows) or something in the bios that i need to setup. How do you properly configure an APU if you are not planning on using the integrated graphics? How do I make sure that my graphics card is running at it's advertised speeds.

PS: Is it safe to run multiple benchmarks? My systems specs are Windows 7 Home Premium 64-bit SP1

8GB of Kingston HyperX Fury 1866mhz cl10

MSI A78M-E45 V2 (recently updated the bios)

2047MB Nvidia Geforce GTX 750 (PNY)

1TB WD Blue 64mb cache 7200rpm

Corsair cx600m

Ok let me tell you about my gaming rig which is also an APU which is the AMD A10 5800K and has a discrete graphics card. When I got a GTX 960, I plugged it in directly and it starts working normally, The integrated GPU is instantly shut off and then I just install drivers and I'm good to go. I don't know about you though, Try going to the BIOS options and see if there is a dual graphics option enabled, It might be the cause to ridiculous stuttering and lags. Oh and try going to device managers at the display adapters section, You must see only the GTX 750 or else the Dual graphics is on. cheers!

Oh and about the unrecognized CPU, It might be due to the BIOS update
