If you are happy then don't change it, be happy and be satisfied

If you are ever not happy you have a very fast computer that is easy to upgrade, for example this would allow you to increase the detail level of the game this card is plug and play and won't be too much for your power supply. You won't even need to remove the old drive, just update the driver to the newer model included in the box.

So if you are ever not happy with your video game performance just send me a nb, upgrading your computer is not that difficult and I can't help you pick out a video card that is either good bang for your buck, or a video card where you don't have to uninstall the old drivers or upgrade the psu. (I also make sure you won't get ripped off )
