Adds up as 541.95 without 55$ mail in rebate and you get a ~5-15% faster CPU and one that doesn’t works as a radiator which means less noise and a much better chipset.
If you still want to go AMD switch the motherboard to this which pretty much is the same thing although much cheaper and doesn’t have a crappy nVidia chipset.

For compatibility reasons you should also get 1.5V RAM instead of non stock such as the Ripjaws which runs at 1.65V. You won’t notice a difference in performance either…
The current case you have listed will probably fry your components instantly due to poor PSU.
Regarding the video card I would either go for a Geforce 460 GTX which gives you quite a performance boost compared to 5770.

If you still want a 5770 get this one instead which doesn’t sound like a lawn mower.
