Hi. First off, Dell is terrible. Here's my current situation: I'm tired of my Dimension 4600, and I'm tired of the crappy graphics, so I went out and I bought myself a 256MB ATI 9600XT. I installed it correctly, and didn't work. I've come to the conclusion that it's due to either a lack of sufficient power from the power supply, or the motherboard's being a *****. So I've decided to gut my Dell and build fresh. This brings up my question. I'm planning on purchasing a case, power supply, and a new motherboard. Now, in my searching for a motherboard to replace this socket 478 motherboard, I've encountered a great deal of diversity between various models. Now, here's my question: if I plan to keep my processor, and just replace the motherboard, do I have to find a new motherboard with matching chipsets and "bridges", or can I just buy a socket 478 motherboard and and a new case and PSU and drop in the processor and flip the switch? (I realize it's a bit more complicated than that) And lastly, if you can recommend any relatively cheap (under or around $80) socket 478 motherboards, I'd appreciate it. Thank you in advance.
