Can I add a good video card to this motherboard with integrated graphics?

Yes it can take a dedicated card. mobos with integrated graphics are set up to override the integrated graphics when a dedicated card is plugged in, It woln't be a problem. You have 2 pci express 2.0 x16 ports which is what all the new and fast graphics cards use, (including the sapphire), you could have 2 graphics cards if you wanted and the graphics cards in question could be linked.

Yes, you can add a graphics card to a motherboard with integrated graphics. Yes, that graphics card will fit that motherboard.

yes you can since the motherboard has 2 PCI eXpress slots. 2 x PCIe 2.0 x16 (blue @ x16 mode,gray @ x4 mode) you have to put the card in the blue PCI eXpress slot.

Yes. The long plastic slot(s) you see near the bottom edge of the board are called PCI-e slots, and the *primary* intent is for Graphics cards...and yes, on some systems, you can install up to 4 graphics cards (called QuadSLi for nVidia, and Crossfire-X for ATi cards). There are other uses, like enhanced Sound Cards, specialised NIC cards, etc... As for the HD 5770...it's the card with the most bang for the buck right now. The matter of "EXTERNAL" vid cards...those are cards external to the case...and while there *is* such a beast, they're not as good as a Dedicated card (an add-on graphics card that is installed into a PCI-e slot). That being said, unless you have a really wonky case, the 5770 is a standard 10" (or less) card. It should fit. Good Luck!

yes, u can add your own graphics card onto your motherboard. and disable the intergrated one. some motherboards do it automatically when u add a new graphics card via pci. agp. pci x16. pci x1. etc.etc. any card in general. but if it dont disable it u can go into your device manager and disable it yourself. even if u dont its not a big deal but it will give you your dedicated memory back. if u want full potential out of your graphics card get a quad core processor 2.8ghz+ and at minimum 3gb of ram. if not you will only get like half of its potential.

You can add a card. I would add an ATI Radeon Graphics card, which would probably work best.
