You wanted the case downgraded to a HAF 922 for a $40 increase in price? Yes, it's a downgrade:

Then, you wanted the power supply upgraded for a $60 increase in price, you're up by $100 and have not yet improved performance.
Finally, you wanted the graphics downgraded at a $20 increase in price? You saw the results, you've seen that these two 470's outperform the 5970 of the previous system.
So, you're up by $120 and have a slower system. I like the that the power supply is 80-Plus Silver rated, but otherwise I'm completely unimpressed by your so-called improvements.
