I would go with your first system, drop the 2 big SSD's for a single 256(which would give you room for your OS and about 200g worth of games), and add a 1tb mechanical for a data drive. The 1000w power supply is also way overkill, you shouldnt need more than a 750w. That would also give you room to bump up to a much nicer video card, maybe a GTX 580 or AMD 7970, and stay within your budget.
