Hi everyone. This is my first post. I have a Gateway DX4840-03c pc and I was wondering if a ATI Radeon HD5750 1024MB GDDR5 PCI-E Video Card would work with it? I've never put in a video card before so I'm not sure what they require. I checked out the required hook ups for the video card but I cannot tell if my desktop has the required plugs. Thanks for the help
