Can i run an ENB mod?

[Goblin]

I run the game on high with AA 8 an AF 8 but i'm still not sure if i will be able to run an ENB. If anyone can help me decide that would be cool. Thanks.

You can, but not really.

You really need at least a 2GB card. I have a GTX 580 1280MB card and even performance ENBs knock me into the 35-40FPS range.

It depends on the ENB that you want. Some are "light" ENB's and they can run on most systems as long as they are gaming systems (you know what i mean by that).
Other ENB's will have the best hardware to date begging for mercy.
Look up some ENB's and see what the creator is telling about performance hit, needed mods and INI tweaks.
Then make a decission on what you want from the game and the ENB. A smooth running game with a heavy ENB is an utopia. So if you prefer smooth gaming go for a lighter ENB and if you like amazing visuals for fantastic screenshots, pick a high ENB that suits your style.

Try Minimal ENB on nexus. Its performance hit is under 10fps.
