Please help with these dual monitor problem

Question

Ok,
Well i am a final cut pro editor and i have a power mac g5 with 1.6 ghz.Its an older one but it runs great for what i need done. Anyway i wanted to go dual monitors so i went out bought a monitor and set it in place. However my graphics card only had 1 DVI PORT (Which had my main monitor on) and the other one was a ADC port. I bought a ADC to DVI-D and then realized it was the wrong one. Those Adaptors are very hard to fine, so i made up my mind a decided to forget that and get another graphics card. However i am not very good with that stuff and i really dont know which one to buy. Some others gave me a list but they were not the same as mine (slots didnt match)
*Here is my card that i have now*

Can someone point me in the right direction about going to best buy and picking up a new one that will hold dual monitors and still run motion at a good level.

If you could find a real ADC to DVI-I adapter, it would work, but the Dr. Botts ADC to DVI adapter
<http://eshop.macsales.com/item/Dr%2E%20Bott/ADCDVII/>
will not work with a DVI to VGA adapter. It does have a dual-link DVI-I connector, but the pins for analog video (and dual link) do not connect to anything. They use this connector because some non-Apple digital displays come with DVI-I and/or dual-link DVI plugs, when they only need DVI-D signals. The Dr; Botts adapter and (all others that I have seen) are only ADC to DVI-D. Even if they connect the dual-link pins from the ADC to the DVI connector, the result will be single-link DVI-D, since no ADC cards provide dual-link signals. There is no reason (other than cost) why an adapter couldn't connect the analog video signals from ADC to a DVI-I connector, but I don't know of any that do.
From their web-page:
"DVI Extractor II makes an ADC-compatible display out of virtually any third-party flat panel display"
Note they say "flat panel".
You need an ADC to VGA adapter. They are listed from $40 to $150. Still less than a compatible replacement graphics card, although you can get a card faster than you current one, if you pay enough.
