What's your operating budget like for this?

I second that. Wait for the new Nvidia cards to hit and see what your price options are. Take what money you're willing to spend now or in a month, set that aside and add a little to that pile every time you get some cash. Once the new cards come out, you'll be able to dump as much as you want into whatever model you think is best when it comes to price/performance.

I personally want the best that there is to offer, short of any "Ultra" version that's announced. That just means I'll be getting the "GTX" version and will be sitting pretty for many years to come.
