this is a popular template build so that you can start from here

game doesnt take advantange of hyperthreading that i7 has

There are a couple things, the Noctua D-14 is unnecessary at best you can still easily attain 4.6-4.8Ghz with the EVO any day.

16GB of RAM will never be used, EVER in any sort of game. 8GB is the staple of today.

The Samsung 840 SSD is slower and smaller (though by a small margin) than the ultra plus I suggested.

You will never ever use 3TB, 1TB is insanely hard to fill no matter what.

670 is 10% slower than a standard 7970, they are also the same price, meaning you get a better deal plus a more overclock able GPU plus better cooling for the same price as the 670. The 7970 is the best value for 1080p gaming right now.

912/922 are interchangeable, you should really pick a case you like not what we suggest, the 912 is just another standard staple of today's custom PCs.

650w will never fully be used, and you cannot CFx/SLI with it, which means in turn you should get the 600w MODULAR PSU that I suggested.

to you both, I noticed you picked i5 processors rather than i7. Any particular reason?

Click to expand...

The i7 will never be used to its complete full potential. Most games do not support 8 cores, but only support 4 instead. This means that the i7 will never fully be used in just about every case. The i5 is the standard in today's gaming rigs, you need no more and no less.

^ dude, you are a veteran here, why not you explain your build instead of making someone's bad and answer OP's question? shameful

I pretty much explained why my build is the best action, if you want a list of facts why mine is better here you go:

Same CPU, perfect for gaming.
Best value CPU cooler on the market right now, you can still easily reach 4.8GHz
Fantastic motherboard for the money
Best HDD for the money right now, really cannot beat that.
Cheap fast efficient SSD, to get the job done
The strongest 1080p GPU out there right now the 7970 is going to beat every other sub 600$ card right now.
The staple case for gaming the 912 is going to be perfect for any purpose with great cable management and airflow
A PSU that will last you a lifetime and longer, also it's modular.
Overall a great computer that will get you 100s of frames a second that is $300 cheaper than any other option presented, and a much better value than the original course of action.

You have a nice budget, but I think it can be spent better.
1. As others have indicated, a 3570K is probably a better usage of funds. The reason is that few games can use more than 2-3 cores, so the hyperthreads of a 3770K will go largely unused, as will the 6 cores of a 3930K.

2. Your GTX680 is an appropriate pick, particularly with your budget. Pick FTW or superclocked version, they are a bit faster with a factory overclock. I like the direct exhaust blower style coolers better than the fan based ones. They get heat out of your case directly. It is true that a GTX670 is almost as fast. But the graphics card is the true engine of a gamer. You might even consider a $1000 TITAN. As to the amd vs. Nvidia issue, my take is that the amd drivers are, today, geared to higher benchmark FPS numbers, while Nvidia is geared more to less lag and better response time consistency.
Here is one of the first articles exploring that issue: http://techreport.com/review/23981/radeon-hd-7950-vs-geforce-gtx-660-ti-revisited
3. No game, by itself will use more than 2-3gb of ram. But, ram is cheap, and I agree with 16gb. Windows will keep more code in ram available for instant reuse. Ivy bridge does not benefit much from ram faster than 1600 speed. Buy low profile versions to avoid any cpu cooler interference.
4. Love the Samsung ssd. Intel is equally good, and 240gb is appropriate. 240gb will hold the os and a large number of games. The 1tb wd black is good, use it for backups, overflow and storage of large files such as video's.
5. Silver arrow is ok. The similarly priced Noctua NH-D14 is a bit better and has very quiet fans. Alternatively, the Phanteks is good too.
6. For the psu, buy only a quality unit. Seasonic is probably the best. 550w will power a GTX680, a titan will need 600w.
I might buy a Seasonic X650 gold rated modular psu.
7. Most any Z77 based motherboard will do. Pick your favorite brand. $150 should be all you need to pay.
8. Cases are a personal thing. Buy one you love. If it has two 120mm intake fans or equivalent, then you will have adequate cooling. A conservative pick would be the Antec 300 http://www.newegg.com/Product/Product.aspx?Item=N82E16811129066 I like the washable intake filters which keep your case free from dust.
I happen to like the quality of lian li aluminum cases. I also like smaller cases.
Corsair, NZXT and Silverstone are other good case builders.
9. What monitor are you planning on using? I might suggest you spend more than you think on a great monitor. Look for a 2560 x 144o 27" IPS monitor. It will be about $600.
