It's not bad, but it's not going to make the card any faster or better graphically. ;) The reason being is: you can have many different qualities and speeds of Ram. For instance you could have 128Mb of wickedly fast ram, or you could have 256Mb of cheap assed slow as an old three legged donkey ram, which is no good to anybody

So, ideally you want 256Mb of DDR3 ram and you have a good card :thumbup:

Hope this explains why more is not always better
