The plan is simple: I have 2 x Intel P4 530 based PCs which I use as home servers. (music streaming, web hosting, FTP, file shares, printer shares etc). One runs Windows, One runs Ubuntu. I want to have a single PC to run all of the above. This is what I think I know so far: Each P4 530 uses 40 watts at idle and 135 watts at full load, therefore I would like the new CPU to be far more energy efficient than these two combined. I would like a multicore CPU as the new server will be running several services 24/7 I would like the motherboard to have onboard gfx that are cabable of running up to 2560x1600 for 2D applications. The applications that will run are: Apache PHP mySQL Java Real Time transcoding of audio Real time downsampling of audio An ID3 tag indexer 4-5 web applications (http, php, SQL, java) FTP server Multimedia Jukebox application My indended OS will be Windows server 2008 Please give me any suggestions for a mobo/cpu combination that you feel would: 1. Save the planet by using less power 2. Give me a nice performance increase over the P4s I run atm Please feel free to make any other suggestions that you think will help me out or to ask for any further information I have missed from this post. Many thanks in advance.
