I know it's cool to have the biggest and baddest GPU, BUT your budget is $430. You can't just buy one exceptional part and then cheap out on the rest. Your computer is only going to be as fast/powerful as the weakest component.
That being said, you have one nice part and then a bunch of mediocre parts. I would work on that. Also, you don't *need* 16 gb of ram. That's mostly for dick-measuring. I usually have a game loaded up, skype, vent, maybe 1-2 other programs and I have never even used the full 8 gb of RAM I have on my computer now. Even running windows and linux simultaneous has never warranted more than 8gb of memory for me. I was looking at putting 16gb into my new build as well until multiple IT professionals told me that it was a waste 99 times out of 100 for people.
:P well I have a 23' touchscreen that this is hooking up too, I`m gonna have a couple of torrents up, maybe 10 tabs of IE with movies in like 3 of the tabs, a few minecraft servers, and usually a game along with skype and background programs like kaspersky. Also I`ll be keeping things like after effects open 24/7. Lol
Also rendering 1080p videos, and saving ones that are about 3 hours long, I record my screen for 3 hours at 1080p for my speedbuilds/codes
