Help / Rate my computer build?

This will be my second build on a computer. I would like to keep it at $1000, but $1100 tops.

I love a powerful multitasking computer that is fast, I would like to SLI

2x GTX 550ti if possible in this build. I like looks but I love performance. Rate this build

and help me make it better within the budget. Thanks ahead of time.
