Definitely go with PC1, After having built 2 pc's of my own, you come to realize that premade computers just don't compare to a computer you built yourself. Personally, if you want high end graphics, the 7770 is not a card that will do the job for you. That being said, you do not need to get a 690, in my opinion it is too overkill. I would go with the i5, and for the graphics go with either a 670/680 or an AMD chip 7950/7970. But if your concern is that you also want peripherals to fit into your budget, simply go with a MSI 660ti Power Edition, you wont be dissapointed.
