With out knowing anything about Jam71868's current system it is a little premature to suggest re-installing everything, and claiming that it will some how magically solve things.
If there is a lot of bloatware running then this can work, but lets find out before telling someone to do a complete back up and re-install of everything.
If he is going to goto that much trouble then he might as well upgrade some hardware at the same time.
And there is NOTHING wrong with Vista.
Reverting back to XP will not improve anything. On a multi-core computer is may even have a negative effect on performance as Vista makes far better use of multiple cores than XP does.
I hate to argue, but after doing IT for 15 years now and many of those years at the desktop level, I need to disagree. In practice, Delete/Re-install is one of the most effective things you can do at this point, not to mention one of the most common and prefered steps in a professional scenario. Bring the system back to a fresh baseline with fresh new file tables, swap space and registry. A reformat is the most thorough defrag you can do. A daul core system with 4gb of ram should be able to handle the 5d MKII raw files with glee.
You should also have your your photoshop swap space setup on a seperate drive array then your system drive(s). That could also make a huge difference in photoshop.
Unless your upgrading the motherboard, it's not absolutely necessary to upgrade hardware at the same time as a rebuild. It's not that much trouble if you keep good backups and have your applications ready to go. I'm not saying this is the only choice, but yes, starting from scratch can do magical things.
Like I mentioned before, I'm doing fine working with multiple 100mb+ images at a time on 1/3rd the system the OP probably has.
Vista making use of multi-core better than XP is just a load of sales pitch to get people on board and upgrade. The only place that is even remotely true is in 64bit, which XP has available as well.



I screwed my schedule up. Somehow I had the meeting down for next Tuesday. I've also been late for two meetings at work this week, too. I gotta get things together, that's for sure...
