Re: Graphics/Video advice needed
Yes. You plug the video card in and attach the monitor cable to the back of the new video card. If everything goes right, it will boot up right away and you'll get picture. Since you're using integrated graphics, the BIOS may autodetect your new video card and just switch over. If it doesn't, you will have to manually go into BIOS setup and disable the integrated onboard graphcs. Then after installing it, your display may look ugly (all bloated with huge icons and letters). You can download new drivers from nvidia.com or use the driver CD that comes with your new video card. As for a power supply, you might be able to use what you have now. How much watt does it have? See if you can open up the case and look on the side of the power supply. Usually, it will tell you how many watt there.
