1. First of all, you need to understand that the performance of the computer is not a single promotion of a part of the quality of the leap, upgrading the graphics card will only improve the speed and quality of the computer's image processing.
2. Please confirm whether your machine is factory pre-installed Win8 or for the WIN8 design of the new Dream series, if it is recommended to refer to the following links to contact the official service network upgrade, if you upgrade your own will cause the installation can not display problems.

3. Before upgrading the graphics card, you need to know whether the motherboard has a separate graphics interface, there are two situations:
(1) The host has a separate graphics card, then unplug the old video card can be upgraded
(2) need to open the chassis without a discrete graphics card to confirm the upgrade slots and space;
Now on the market more popular graphics card is PCI-E interface, you can in the case of the host does not connect and cable, carefully open the host box, pay attention not to artificially damage the internal components of the host (if it is man-made damage can not be guaranteed), see the Motherboard interface as shown below:
In the image above, the black slot is the video card slot, if the motherboard does not have this slot, then you can not upgrade the video card Oh, there is a video card slot, please continue to look down;
4. To upgrade the graphics card also consider the following two aspects: the internal space of the chassis, power supply is adequate, internal space, in addition to the small chassis of the model, the new Dream F Series Basic is no problem. Power, because some graphics card needs more than 100W power supply, but also need to power the video card from the source separately, so the general standard power supply is not enough, to upgrade the power of a larger graphics card when you have to consider the replacement of the power supply, otherwise it is not available oh.
5. If you solve all the above problems, then congratulations, you can upgrade the video card, and finally remind you that the upgrade hardware will have a small probability device incompatibility exists, please purchase before you buy (the best way to detect compatibility is to install to the host test)
