I have an issue for the amount of faces I have, I have made a decent looking character with blender (just the head) so far. However, I finally get to the step where I need to add textures and I mark my seams and unwrap, my whole computer freezes and blender crashes. I have ~393, 000 faces.
I would really like to keep my work so far, instead of redoing it for the 4th time, is there any way I could keep my beautiful work of detail and awesomeness but decrease my faces.. but still keep my work, and have it still look good when I render it in Blender Render?
This is how it happened, I have a little issue with hitting the subdivide button alot, not the one in multi-resolution but the other one. And that's because I love detail.
Here is an image of the issue..

I would really like to add hair without the lag too~ :(
