I guess I should clarify the point I was trying to make on WB.com... For video editing alone you do not need a super fancy video card like this http://www.newegg.com/Product/Product.asp?tem=N82E16814170088
(unless you are doing 3-D or some serious gaming.)
Here's an example.. In year 2000 my editing system was using the matrox dual-head video card with only 32 megs on-board memory.. Most cards these days come with 128…
1) Do you want to do 3-D, CAD, or gaming?
2) Do you want to run multiple monitors?
If you answer "NO" to both questions above then you can get away with most video cards. Just make sure to find one with the correct interface for your mobo (AGP 4X/8X, PCI Express x16, etc..) and with a DVI out for you monitor.
