Like you, my pc is not that all great to run tons of mods like alot of people can, so what I did first, was look for ENB's that didn't hit hard on my fps and also looked good. I tested alot to find one that met both requirements. After that, I tried some textures too see how far I could push it, without sacrifincing too much. Also, people that run with tons of mods only do it so to take screenshots, in most cases, it's almost impossible to play with too many effects together. I remember a guy by the name of Shunreal, he's screenshots were amazing, and his computer specs were also impressive and still, when he fired everything up to take a ss, he said he's fps would drop from 60 to 10. So, in the end, it all depends on what you want, be able to play with somewhat good looking graphics, or just take ss to show off. If you allow me, those are my favorites ENBs: http://skyrim.nexusmods.com/mods/24828//? http://skyrim.nexusmods.com/mods/15425//? http://skyrim.nexusmods.com/mods/30158//? http://skyrim.nexusmods.com/mods/21123//? http://skyrim.nexusmods.com/mods/15105//? and sadly the one that I'm using atm was removed by it's creator.
