    It will work fine with your CPU. That said, you really should consider upgrading your entire system as the Core 2 Duos are quite old and regardless of the GPU, can't run many newer games well, if at all.

    To run the 7770, any decent 400W psu or better is all you need. It will also require a 6 pin PCIE power connector. There are molex to 6 pin adapters for sale and they will work fine.
  2. Yes your processor is 2.8GHz and i'd reccomend a 450w or higher power supply.

    I'd reccomend upgrading your processor though since it may bottleneck the HD 7770 slightly.
  3. Hi,

    the gpu is fine but your cpu and even with this gpu you won't be able to get much more FPS for those games.
    +1 you might need to upgrade your PSU.

    Thanks and What does the term "bottleneck" mean ? And can i overclock my processor ?
  6. All of the core 2 processors, be a dual core or quad core aren't enough to run current demanding games at any acceptable frame rates regardless of the GPU.

    You need a new motherboard, CPU and likely memory.

    A bottleneck means that you have one component that starves another. In your case, your CPU is very slow. The 7770 won't be pushed to it's full potential because your CPU can't give it information quickly enough. Therefore the 7770 will be waiting for things to do while your CPU is constantly trying to catch up.

    It's like if you pinch a straw, it restricts the flow of the liquid. The pinch is the bottleneck, in your case, the pinch is your CPU.
