After combing through some of the other graphics cards I have come up with these updates:
Graphics card: MSI GeForce GTX 670 2GB Video Card
Memory: Corsair 8GB (2 x 4GB) DDR3-1600 Memory
Power Supply: CoolMax 600W 80 PLUS Bronze Certified ATX12V / EPS12V Power Supply
That's it! That's a much better than the original one you'll be happy with that one as it will perform much better.
