I currently have a z800 and the wife is doing video editing large files, we have the single processor, it has the x5650 chip in it and were looking to put the 2nd processor in it. My question is would we be better served putting in the x5690 chips in it, boosting the memory to 144gb. Or just adding the 2nd x5650 chip with the upgraded mem as well and call it a night? Also is the x5690 server chip ok to run in the z800 computer? Or is it the sdame chip? Right now it has the x5650 (1) chip in it with 32 gb of memory running a nvidia fx4800 video card, we want to switch to the quadro m6000 as well. Thanks in advance for everyones input.. Dennis
