This week has seen a lot of movement in the graphics card market which started with the launch of NVIDIAs GTX 560. The main impact of that release was an adjustment of prices on AMD based cards to ensure they were as competitive as possible and then there was the release of 6950 models which use 1GB rather than the standard 2GB. At the same time we have also seen a number of manufacturers begin to hit the market with their enhanced 6900 series cards.
