I'm building a new dual processor workstation and I'm trying to find a pair of socket 771 xeon processors that are under $300. I'm looking at the following: xeon 5120 xeon 5320 xeon 5060 I'm leaning towards the 5320 since they are quads. The 5120 are cheaper but dual cores; the 5060 are higher mhz but have the 667 fsb. Main use if for video and audio capturing/editing in Adobe Premiere. Any suggesions or other choices would be a big help .
