I would stick with the EVO cooler as the Noctua is not worth the extra IMO.
I would also not wait on Nvidia. It may be the end of the year, and rumor has it, they will still be slightly behind.
For the monitor, 24" is an odd size. 23" is more common and usually a better deal. With the 24" you will likely have top and bottom 1/2" black bands which would negate the extra inch. I know I have this issue with my 19" Samsung. The best advice on monitors is to go see one in person. The one your eyes like is the one to buy regardless of price or brand. They all have about the same warranty, although Samsung is very good about service. Once you find the right one, you can search online for best price.
