I'd recommend a 750 Watt PSU, and I think skyrim should run pretty well with recording software. The only real way you get better performance is with a high end GPU (Graphics card) But for skyrim your comp is /gewd
I know recording a bit. So here's some tips that could help you on your future recording. (Assuming you don't know them already)
Always recording at 30fps! YouTube doesn't support 60fps video. If you do upload a 60fps video, YouTube will scale it to 30fps. Not to mention the file size of 60fps videos is gigantic. I got a 400GBs for 30 mins of New Vegas footage. (Assuming you're uploading it to YouTube. I use "scale" because that's my poor English, someone please give me a word.)
Record it in 720p if possible. Most people screen don't go up to 1080p, so it's pretty useless to record a 1080p footage. (Not to mention the file size is pretty big.)
Render it with Video Editing Software's. It helps out A LOT with file size, making uploads so much easier. There are some pretty good Free ones out there, but you could always pay for Professionals Software like Sony Vegas.
I think that's pretty much my tips. Anyway, this is my specs: (Currently anyway, I'm planing to upgrade it soon.)
P8P67 LE Motherboard
Asus HD6870/Asus EAH6870 DirectCU
PSU unsure. Will check now. ...After I know how to get my case open...
And my framerates on Ultra is really bad, it's about 20-30fps, which makes it unplayable. But playing High gives me a stable 60. I'm running in on 720p. (Don't have a 1080p monitor. :sad.gif: ) My specs could give you a comparison, even though it's not much. I hope I helped.
Edit: No screwdriver. lol. Looks like you solve your problem anyway.
I have the same CPU and GPU in my build at the moment.
I can play it on High smoothly, not too sure about recording though.
You should bump up the 2400 to a 2500k.
Also, a 620W PSU is plenty; my build is running on a 500W.
Drop the 16GB of RAM to 8GB, since you won't even need more than 4GB (had 4GB in mine for a year and never had any problems), and RAM is so cheap these days.
Also, Sandy Bridge likes RAM in 2 slots, not 4. So you have a problem there (unless you change it to 8GBx2 which is really expensive).
And are you sure you'll need 2TB storage, especially considering today's HDD prices?
After having mine for a year and installing quite a few games, I've only used 230GB, for example.
Just get 1TB now, and the other 1TB later when you need it, as it'll be much cheaper then, and you probably will never need to buy it anyway.
This is assuming that you don't mass download porn and such.
