I have put together (from various retired computers) a little PC with a 775 socket motherboard. I currently have a pentium E2200 or a C2D E4500 laying around, but can get an E8400 cheaply off ebay. I'm wondering if this would serve my needs, or if I should get a C2Q for a little more. High end C2Qs are out of the question, as they simply cost too much compared to core i stuff. Which ever I do, it will be coupled with a cheapo GPU (HD 2400 Pro) until I can get something with HDMI out cheaply.
As for what I would like to do with it, I would mostly like to rip (some of) my 1000 or so DVDs and Blurays onto some HDDs (not thinking about this yet, RAID or whatever) with a nice front end. Streaming and some light emulation maybe as well.
