By matching, we really mean down to the Brand.

Buying the appropriate memory is easy, and I would help you.

Installing a video card also is not difficult. For a high-end card, there is a power cable with either four or six pins (or eight, but probably six pins in this case) that must plug into the back end (or the top) of the card. The pin connectors are set up so that it can only go one way - no worries.  There will be the appropriate power cable coming from the power supply, and it almost always will have a little tag on it saying "PCI Express."

To install a video card, you first plug in the little power cable. Then you set the card into the slot on the motherboard, pressing downward until the card clicks into place. Then, there usually is a bolt that you screw into the metal tang at the head of the card, that locks the card to the computer case. Typically, you require a Phillips screwdriver for this. And, that's all there is to it. Another "no-brainer."

And Melikia, if you are capable of operating Vue to any decent effect at all, you are intellectually and physically capable of installing a video card - LOL!

There will be a DVD or CD with the video card, you put it into the DVD player, and let the autorun bring up the process for installing the card's software drivers. These days, the software does all the work, and you just have to follow the few on-screen installation instructions. Honest!  That's all there is to it!

Actually, if you can operate Vue and make a decent scene, you are physically and intellectually capable of building your own high-end computer.  But that's another story..........
