Two changes I'd make. First is a minor one, consider this set of RAM which is slightly faster (thought not noticeably for practical purposes) and also $10 cheaper.

Second, you can do better than that on the power supply, also for less money. XFX 550w unit on sale for $26 after rebate, a real steal at that price for a very solid PSU:

edit: that is the same PSU mentioned above, just at a different retailer.
Also, I would not worry too much about a high-end motherboard because 1) You aren't overclocking, and 2) You're using a single-card setup. It might be better to get out of the bargain-basement range as the person above me said, but don't go crazy for some $150 job either.
