[Bottleneck] Question regarding ASUS HD7970-DC2-3GD5

Hi there TH, I'm a regular visitor to the site for most technical info in regards to GPU's, CPU's, RAM and other hardware needs, as well as the odd software problem or question. This would be the first time I've come forward with a question, and all input is greatly appreciated.

After much debate, I've decided that if there isn't too much of a problem with my system beforehand, I'll be buying an ASUS HD7970-DC2-3GD5. This is the site I'd be ordering it from.
My current system specs are as follows:
CPU: Phenom II x4 955 Black Edition @4.0GHz (37degrees Celcius idle, 53 max full load)
RAM: Avexir 8GB (2x4GB) 1333MHz@9-9-9-24
Motherboard: GIGABYTE 990FXA-D3
OS: Windows 7 Ultimate x64
PSU: Cooler Master 700W (52A on the +12V Rail)
Current GPU: HSi Radeon HD 4770
Display: Generic 32" LCD TV - 1600x900@30Hz (Occasionally 1920x1080@30Hz)

My only real worry is whether my CPU will bottleneck performance of the new GPU on one display. All other information is likely unneeded, but highly welcome. ;)

  1. Ah, was wondering if that would be the issue. I do have another monitor in storage that runs at 1440x900@60Hz, just my current one was the generation below the 1080p mainstream generation...sadly. Heh.

    Ah, while I'm on the topic, do you have any advice on how I should go about slightly raising the clock speed of my CPU? More specifically, which exact parameters should I be focusing on. Currently, I'm running:
    HT: @2200MHz
    NB: @2200MHz
    Clock Multiplier: @20.0
    Bus Speed: (Normally) @205/206
    Core Voltage: @1.440V

    Any advice is appreciated, though if needed I can jump over to the CPU section, thanks.
