I'd recommend against the GTX 295 simply because it's old tech and Nvidia's new lineup is just around the corner, supposedly by March/April. Since Dolphin isn't GPU-intensive, you could get a 9800GT for ~$100 to hold you down. Try looking for an eVGA of BFG branded card as well for the step-up program.
Get an aftermarket CPU cooler too and overclock that 750. It'll help a lot with Dolphin. Everything else looks fine though.
Btw, where are you buying all your parts? There may be some cheaper places to check.
