If you believe that Skyrim's graphics are limited to it's size, you're badly mistaken, texture mods should show you that. Texture quality has zero impact on performance, assuming you have the VRAM and texture quality setting are only there for cards with lower VRAM
Yes and the game already is topping the standard VRAM Size for the average PC. I have used Texture mods in other Bethesda games and trust me there is a performance hit, if you do the high end Oblivion Mods you can bring even a top rig down to where it acts all crappy.
