Alright some (very) brief history on me and my load order;
-Have used mods for Morrowind, Oblivion and Skyrim (both fallouts as well) and their respective utilities.
-Have a personal archive of mods for Skyrim, which I have used before without issue.
-Have the latest official patch.
Basically my issue is that after about 5 minutes time in game the FPS drops low enough to become, quite literally, a slideshow. I've used this batch of mods before and only had the most minor of issues (mostly a CTD once or twice every 4+ hours). And I have done a lot to try and troubleshoot this but I cannot figure it out. I'm just confused/concerned and hoping that it isn't really bad news. I.e. my hardware is having issues. So please, someone tell me I'm just being dumb and made a really obvious mistake with my load order and/or choice in mods.
Edit: Also, it is like this on new games and old save games.
My system specs:
AMD FX-8350 (stock speed with extra cooling)
8GB ddr3
Radeon 7870 (2GB)
Skyrim installed on a 7200 rpm Harddrive
