I'm using the ASUS GTX 660 GPU, 8GB RAM and an AMD Phenom ii x4 840 3.2GHz.
The problem is, I got decent FPS on my previous graphics card, but now I have upgraded, my FPS has gone down to terribly low on most games (10-20 fps). The games I get bad frame rate on are:
Borderlands
Arma 2
Planetside
Loadout

The games that run well are:
Battlefield 3
Minecraft
Call of Duty 4
Source games

I thought it may be due to my processor at first, but after seeing my brother's FPS compared to mine (he had a worse graphics card and slightly better processor), I assumed the difference was too large. Maybe It could be a software issue? I'm not good with computers at all, any help would be great! But please dumb it down a little!

Run Afterburner and check your GPU usage. If you are running at 99% GPU usage in that particular game, then you have no bottleneck. If you are running at less than 99% GPU usage, particularly if its closer to 50% or less in that particular game, then you have a CPU bottleneck.

Okay, so what would I do to resolve CPU bottleneck?

I just downloaded afterburner and tried cranking up the settings, it seemed like it was going to run really fast, but when I go into a multiplayer game, the screen went black (in the game with the HUD etc still there), I had to restart my computer. I think there may be promise and I just have to fiddle with the settings until it works!

It is especially important to fully uninstall the old drivers if you are swapping from Nvidia to AMD or vice versa like this:
Download and save-do not install yet-the latest drivers, in this case from the Nvidia official website.
Download and install a copy of Driversweeper or Drivercleaner.
Uninstall the current drivers and restart in Safe Mode.
Run the drivercleaner software in Safe Mode but CHECK EVERY ITME THAT IS TO BE DELETED! It is not unknown for these programs to delete system files.
Restart normally.
Install the drivers you downloaded earlier.
Restart.
Done.
