That looks like a good PC made with top notch parts, The RAM if you ask me is overkill. You can get a similar 8GB kit for half the price. Of course you can keep the dominator plats too. I have 6GB in one of my rigs (3x2GB) and they overclock very nicely. Perhaps the best memory, but the philosophy for most when it comes to RAM is if it works then it works, no need to buy the more expensive RAM.
