Ok, so I want to add another video card to my computer so I can have a dual monitor configuration. My computer is dual core, so does that mean I need a dual core compatible video card?

Computer Specs:
-Dell Dimension E521
-Dual AMD Athlon 64 X2 Dual Core Processor 3600+ 1.90 GHz
-958 MB RAM
-Windows VISTA Home Premium 32-bit
-NVIDIA GeForce 6150 LE video card

Thanx

EDIT:
Ok, I found a supported HARDWARE wizard on AMD's site. I did it and found that Radeon graphics CARDS are supported on AMD processors (Offcourse), but does that mean all AMD processors can support Radeon or some? (Such as dual core) Here are the results of the wizard.what you need is to make sure that the video card you get has dual ( DVI-connections) thats it*

your going off base with the dual core compatible issues.............

Like honvetops SAYS, there are no compatibly issues between graphics cards an dual core processors. If you can plug it in, it's compatible.Well, what about graphics cards that need a processing speed of 2.4 GHz or faster? Then compatibility becomes a factor right? If this is true, I need to get a graphics card that can run at my processors speed, right?Your CPU is equivalent to faster than 2.4GHz, don't worry about it.
2.4GHz refers to the equivalent P4 speed.

As honvetops said you just need a card with dual DVI connectors for dual monitors (assuming your monitor uses DVI). Then you can disable the onboard video.The only thing you need to worry about when dealing with dual core cpus is your motherboard. once you have a motherboard that is compatible with a dual core cpu, your good to go. with other hard ware there are programs that allow you to use dual video cards ATI has Crossfire and nvidia has SLI, but dont confuse that with dual displays even though they allow you run dual video cards you have both cards working on 1 display. you dont plug a monitor into each card. it still works like 1 GPU. it is for preformance of 1 not running 2 displays. like some one said earlier make sure your video card has has a place to plug 2 monitors into it
