Framerate issues, debating an upgrade

Hello all, I have a 15 inch Macbook Pro with a AMD Radeon HD 6750M with 1gb of VRAM, 4 GB of RAM, and a 2.2 GHz i7 processor. When running WoW on recommended settings, or even when I tone down the settings, the framerate is at a constant 15-25 fps, 30 if I get lucky. I wanted to know if there is anything I can do to fix this.

I'm thinking about purchasing either 8GB or 16GB of RAM to help the framerate (as this is the only thing I am able to upgrade). I am not sure if increasing my RAM will help with this issue. Any suggestions would be appreciated.

Have the same model and can push to 80fps (even tho I cap it at 40fps) on the 15" display and have playable fps when using the LED Cinema Display. You might want to investigate your problem before you upgrade anything.

Also I'm experiencing the 'pulsating' bug (only on that device and not on the other 4 Macs that have installed WoW in my household).

How would you recommend investigating it?

- restart in safe mode then restart in normal mode (indexing can cause issues)
- reset SMC
- make sure you have installed smcFanControl and it's rotating at 4-5k/sec while you play WoW
- go into your logs (launch System Information in the Utilities folder) and see if there is any error
- install geekbench (CPU benchmark) and Cinebench (GPU benchmark) to make sure the hardware works
- make sure your settings are low (stuff like fluid effects and shadows *destroys* fps on OSX)
- check in the Activity Monitor/System Memory/Page Outs, a high value might indicate that you need to either launch less applications with WoW or add more memory
