A buddy of mine ripped his onboard video card out from his motherboard. I tried replacing his video with a PCI card but, as I learned from you intelligent people, that's a no go. So, I'm looking to replace the MOBO. I'm not that computer savvy when it comes to knowing what other Dell models have compatible MOBO that I can just replace the broken one with. I understand that I'm going to need swap the processor but would a different dell model like the 4550 work? Thanks in advance.
