Which Video Card fit for Intel Dual Core?

Any video card will fit for Intel Dual core unless your power supply is capable enough to run it. The type of video card doesn't depend on the processor. Its basically depended on the motherboard PCI-E slot and power supply. So, if your motherboard has a PCI-Express(or PCI-E x16) card slot and and a good branded power supply with enough wattage, then any card will fit in it and run smoothly. If you have under-powered or local made power supply, then go for less powerful cards or upgrade the power supply first. Today, we have only 2 major video cards maker. Nvidia and ATI. Both cards are good but it all depends on your budget and the rating of your power supply.

i suggest you to use nvidia product if you use intel product. though you can use ati product too, but every notebook product give specs of pair with amd and ati or intel with nvidia. i don't know the details. as i know, geforce have lower voltage than ati. good luck ^_^
