I know you said you aren't an ATI person but I must insist that you please reconsider after seeing the following link as it works better for your budget:
http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Order=BESTMATCH&Description=ati+radeon+4770&x=0&y=0I was originally going to get the 9800gt but I reconsidered because of this beauty
Advantages over the 9800gt:
45nm core and thus
-Less Heat
-Less Power consumption
-Overclocks better and more easily
-Works better if you crossfire it
And to be blunt, the 9800gt doesn't beat this card in a single category. I am serious, if you look at benchmarks, this one smokes Nvidia's card in every test. In fact, the reason why the 9800 is so cheap now is because of this card.
This card was so popular that I had trouble being able to buy one since they sold out so fast. Now they have been re-released with an even better heat sink for the dual slot cooler.
Please consider. I myself have found it to be a remarkable graphics card and it has been very trusty for me since its release. Only hangup is that you will need to reconsider your mobo...
This one caught my eye:

Intel/Nvidia is better if you are going higher up and getting a more powerful computer. For 700 dollars, you can stay with Intel, but I highly recommend getting ATI instead of Nvidia. The mobo's come cheaper and the graphics cards are cheaper without a noticeable difference in quality.
I also approve of your choice for processor, and for PSU. I haven't had any experience with the company you chose for the case or the memory though.
