I5 2500k budget build

This computer will be for some gaming, video streaming (Netflix), and general purpose use.
I wanted the option add a 2nd video card down the road, however i probably will never do it.
I was considering SSD, but will probably wait on that
I will not OC immediately, i may later on, but it is not a given.
The purchase will take place in a couple weeks.

its in the $930 usd range

its a little higher than I would like. I was aiming for the $800 range w/ the OS.
I would like some other options with the mobo & memory to maybe bring the cost down some. The GTX 460 is also on the chopping block if i can find a replacement that will offer the same performance. with that said If you choose a different GPU for me than please make sure the mobo will support whether it is SLI or Xfire.

edit: I will also be purchasing a 18.5" monitor and screen resolution is unknown

I welcome any advice.

thanks
