GPU: ( I am totally open as far as manufacturer goes, but like the numbers Tom's gave this card)

Just a heads up, you're not going to be able to run RAM at more than 1333 MHz unless you OC your CPU. The i5 750 only allows a memory multiplier of x10. With the stock BCLK of 133 your max memory frequency is 1333 MHz.
If you get 1600 MHz RAM there may still be some advantages - you might be able to run it at 1333 with tighter timings or with less V so there may still be some value there. And it will have the extra headroom if you do decide to OC. (Of course 1333 RAM is OCable too you just aren't paying for the manufacturer guarantee.)
A lot of people get 1600 with an i5 750 and then are upset when they have to OC their CPU to get to 1600 MHz so I thought I'd warn you now.
Thanks for the heads up on the CPU/Mobo combo.
I think I'll go with the G. Skill Ram after reading a bunch this AM.....
When I did a quick calculation for the PSU, it seemed that 700W would be sufficient even if I wanted to XFIRE later, but from your posts above, I may need the extra 50W.

thanks to all for your input. I ended up with the G. Skill Ripjaws Ram (4GB) and switched to a thermaltake 850W modular PSU so I'd have no worries when I crossfire later.
also went with the 23" monitor that kroeters suggested.
I'll let you know how it all works in about 3 days.
