Ok, to start off I know pretty much nothing about motherboards, however I want to change the motherboard in my Dimension 3000 to have a PCI-E slot, it also all started when I got BF2 and it wouldn't run on my current PCI card, and everyone recommended to get a new mobo, and a pci-e card as that would help in the "long run," so thing is I want to keep my Dimension 3000 Case and I want a motherboard that has a PCI-E slot (sorry for being reptitive) so I want to know what mobos would fit the case, I heard that the Dimension 4700 mobo would fit the case and run with the rest of the Dimension 3000 equpiment, is that true? As I've seen the 4700 mobo on ebay for around 70 bucks, if no what other mobo would also fit the case and run with the rest of the Dimensions 3000 equipment, and wouldn't require anything such as a new power supply? And one more question, would the new mobo + a pci-e graphic card, good enough to run Battlefield 2, all together cost more then $150? As I'm only 14, got my Dimension 3000 not long ago so I don't want to bug my parents about buying me something for it ago, and I'll be using my own money for it, so for me the cheaper the better, any help input and help with this would be greatly appreciated. Oh and if this info is needed, my Dimension 3000 has a P4 3.0Ghz HT Proccessor + 512MBs of RAM.
