The usage of mod organizer removes these restrictions completely. Steam Workshop still has its own caps, though they seem to be easing up with recent updates. The 3.1 gigabit RAM requirement is addressed by patches in various places. ENboost and the latest SKSE version handle it well. :edit: You mentioned ESP specifically, but it didn’t work for me initially—sorry if that was confusing.
Textures consume significant memory (RAM). With around 50 textures per mesh or graphics mod, your GPU will be nearly full, and adding more mods will push you past the 3.1GB threshold. Are you considering raising the crash limit to a higher value?
It's important to monitor your VRAM usage to avoid reaching the 4GB 32-bit limit. Ideally, the upcoming TES game should support 64-bit, which would eliminate memory constraints. (Also, not every texture is loaded simultaneously, so a full 4GB texture pack won't consume nearly all VRAM unless you manage asset loading efficiently.) The SKSE patch could push usage slightly above 3.1GB, but it's unavoidable to stay under 4GB since the application is 32-bit.
Sure, I understand you're asking about Skyrim's performance with your processors. It's worth noting that Skyrim doesn't heavily utilize multi-core processing, so the difference between your i5-4690K and i7-5820K might be minimal in terms of gaming speed. Focus on what matters most for your needs!
