I prefer this monitor but it's more expensive so I won't recommend this but it's something you can opt for instead of the Acer.

The Biostar seems to have got good reviews and actual manufacturer's response to those who gave it like 1 egg so I'll stick with it. I don't suggest dropping to a HD 6850 because I think you'll only save around $10 to $20 at most and the 6870 is a really good card.

If you're really not going to overclock, you can safely drop down to a core i5 2400 along with a H61/H67 and that will save you a lot fo money. I do recommend overclocking the i5-2500k, it will be a good experience for you and it's easy too! The CPU is well-known for its easy overclockability and awesomeness  

Well turns out my mom already ordered these parts  . So could i possibly make my current specs work?

^ All compatible. Can you return them?

You kind of spent more than you needed to. IE. Power supply, I think the GPU was a bit pricey for how much it performs. The 550 Ti would've saved you a bit of money for similar performance. You're not overclocking or SLIing so you don't need P67 or the 2500K. You could've saved around $90 by dropping down to an H61 and a 2400.
