I'm looking into building a new machine strictly for photo editing. Our current machine we've had since 2002-2003 and it's just not fast enough to handle running Lightroom, and photoshop. From what I can gather, gobs of RAM is a must... I can handle the vid card, HD, DVD burner and RAM, but I'm clueless when it comes to the Motherboard, and CPU/Processor. Any tips would be greatly appreciated.
