Installing a Graphics Card

[AdamBragar]

The most advanced technical work I have done on a computer is plugging it in. I just purchased the Dell 30" widescreen and I need a new graphics card to support it. How difficult is it to install a graphics card? Would it be smarter for me to have someone come in and install it?

Any help would be greatly appreciated.

P.S. If graphics card installation takes technical expertise and you live in New York City and can help, I'll pay for installation. PM me.
