The guys at maingear.com put this one together for me. P4 2.8GHZ with HT 1 gig ram I am running 3 260gig hard drives dvd burner geforce 4 card built in sound lots of stuff hanging off via usb (webcams, video editors and so on) I pretty much never drfrag my drives, run all NTFS partitions. I do not run in administrator mode to avoid most virus danger as well as running a good firewall too. I am ALWAYS running Outlook, photoshop CS, MyIE2 (tabbed browser extentsion for IE) with 30+ open web pages and usually Max, Maya or Poser. Rock solid, day in, day out. It was great with Sr3, it is better with Sr4. And yes, I frequently do animatiosn in Poser with hundreds of frames for dynamics tests on a project I have in the works.
