Also, Tom's did a nice build under 1000$ in late February that might be helpful to you. It will at least give you a basic "where to start" thing.

Here's the link: http://www.tomshardware.com/reviews/build-a-pc-performance-overclocking,3437.html

Scroll down the page to the bottom and you will see a dozen or so thread links with $1200 builds

Yes but that monitor is only decent at best. Get an Asus VH236H instead - it's a far better purchase for like $15 more than that Acer.

I swapped out some parts from the build linked earlier. The CPU/Mobo were swapped to something else which will give you the same performance but not the overclocking ability since it was stated you had no interest in overclocking, while still giving you a mobo with USB 3.0, 1x 6.0Gb/s Sata. Heatsink was swapped as well to something cheaper which will provide more than adequate cooling as you don't need as much due to not overclocking (even if you kept the hyper 212+ I don't think you see any difference except mabey a couple celsius compared to this one). Ram was swapped to something with same cas latency but DDR3-1866 vs DDR-1600 and its about $20 cheaper. Case was swapped out to a cheaper one which still provides good cooling capability just buy the fans. GPU was swapped out to a GTX 670. PSU was swapped to a different one which was cheaper one, same brand and power rating. Monitor was swapped to one which better brightness and better response time so you don't get any ghosting while gaming.

EDITED IN:
Forgot to look at the hard drive, heres another $20 saved

That cooler you chose isn't any better than the stock fan. Stick with the 212 Evo - it's more than worth the extra $20. If you're paying that kind of money for a system you severely limit yourself by not going with Z77 and the 3570K. Having B75 and a not-unlocked 3570 will hurt your long term plans for your system. Go with this instead:

Actually from some of the reviews I've seen in the past the fan is actually better than stock. There is also the fact that it provides direction to the airflow so it flows air out of the case instead of recirculating it throughout the case which the stock fan does. The CPU is 77w, not to difficult to keep cool so I see an 212 EVO as overkill, especially when the 212+ goes for $20 right now and the difference between those 2 are minimal.

Going with a 3570 and B75 motherboard doesn't hurt performance in comparison to the 3570k and Z77 when you don't plan on overclocking and from the looks of it doesn't need any of the additional features the Z77 provides over the B75. (op stated he wasn't overclocking and I suspect used the K processor due to that was used in the system builders build as there are some similarites)

There is also a pretty good premium your paying on parts which aren't giving you a performance increase compared to what I posted especially when you take into the account there is no overclocking. CPU/MOBO/Heatsink/PSU/RAM. And If we take out the OS and Monitor out of the picture my build comes to $860 but lets say $880 as you still need fans for the case after rebates vs $945 for your build (didn't bother checking to see if it needs additional fans),or roughly $910/930 vs $975 not including rebates.

But due to the premium I am not paying on certain parts I am able to put in a better GPU and slightly better ram. GTX 670 vs 7950, and DDR3 1866 vs DDR3 1600 both cas 9 ram with heat spreads and from respectable companies.

So my question is why do you recommend going with the Z77 and K processor and paying the premium prices for that and other parts which don't give you any performance boost vs using that money for better performance parts from the get go.

(Sorry if it sounds I am trying to pick a fight, not my intent. But I am just trying to figure out why you are choosing these parts as I am curious.)
