30 inch Dell Will this work on my computer.....HELP PLEASE

No. Two different card types. One is PCI (the old one from years ago) and the other is PCI Express, a newer more capable card type. Not interchangeable.

 

I stand corrected.

Dual Link refers to the type of cable, not 2 cables.

I was wondering about that

Thanks for the pics that's helpful I'm going to 2 x 30" next.

 

No no no. It is not just two different cables. Look at the connectors on your card. I guarantee it looks like the DVI-D single link. Simply buying DVI-D Dual link cables won't suddenly make your old card Dual Link capable.

 

If you use the vga connectors you'll get a higher resolution

 

not on a 30 incher you won't. You cannot even run its native resolution on anything but dual link DVI. VGA doesn't even go that high. No VGA card does.

 

if you have 1500$ to shell on a 30 inch screen you can afford a 500$ new motherboard + cpu + ram + compatible video card.

 

Not quite right. "Dual link" is for running 2 video cards to power 1 monitor... there is even a 3-card setup by Nvidia to run 1 monitor for extreme gaming.

For multi-monitor trading, there will be no "dual link" utilized. 1 dualhead DVI video card, with appropriate resolution params, will run 2, 2560x1600, 30" monitors.

 

i will start buying somewhere around 50 LCD inches. i don't think i have too long to wait.

 

Oh yes you do. A 50"er would be a Bazillion, Gazillion pixels... not in the pipeline anytime soon.
