Is this PC good

I suggest the NZXT Krakken or Corsair h100i GTX for cooling... both are cheaper and work a lot better. The GPU cards in SLI will work very well, although i have heard really good things about GTX 960 4GB in SLI.. that would save you almost $300. I would just look into that. I have the white H440 and it is a beautiful case. Excellent choice with that. Other than that it should be a beast of a computer. If you want to add some aesthetic, buy a few LED Light strips to add in the window of your case. I added some and it looks awesome.
