Thanks. Yeah, I think I've taken a look through there before; taking another one now though in case I missed something I'd like to use.
Windows performance isn't really an issue for me though, but I have tweaked it a bit for how I use my computer. For example I don't use the paging file (generally not a good idea to do this, but it works fine for my needs).
I still have a HDD (though I have a lot of it cached by SuperFetch) as my main drive. Holding out for a 1TB SSD when they drop in price enough for a quality one. Then I'll just use the HDD for backup.
I have a pretty large RAM drive too, and run a Minecraft server on that. Looking into using it to record uncompressed HD video+audio too.
This is all while I keep my CPU and GPUs dynamically fully loaded crunching for BOINC in the background, so my computer is up and running nearly 24/7. I can also remote desktop into it on my Nexus 7 tablet from anywhere with Wi-Fi to check on things.
