I have recently gotten a cam which shoots in HD. Yee haa. =However my PC is dramatically underspecced to handle laying HD and editing it. I intend to upgrade to an i7 and wondered what graphics card would be best suited to use with it? How much power from the GPU do I need for viewing HD and editing it or is it all down to the CPU and memory. I don’t intend to game so don’t want to spend loads on a card which will not be needed?
