building my new pc ( your thoughts options etc..)

Instead of a 3TB 7200, get a 1 TB 5400 and a 64GB Samsung SSD like 840 or 850.

On the SSD you install your Win while all the programs will be installed on the HDD. W/o an SSD your PC will be outdated in a couple of years.

I made tweaks to it: http://pcpartpicker.com/p/bX8jkL price went up a bit, but you will get a bang for the buck.

Changes:

• Downgraded CPU to i5 4690K (Reason: an i7 is really needed if you want to stream/render)
• Changed memory to Corsair Vengeance (Reason: to save a few dollars (use promo code: EMCATAX74))
• Changed Kingston V300 to Samsung 850EVO 250GB (Reason: Kingston V300 did a bait & switch move, newer units are using a crapy NAND which is barely faster than a WB Black hard drive)
• Changed Seagate 3TB for WD Black 4TB (Reason: 3TB Seagate units have a higher failure rate)

All other parts are untouched.

NOTE: If your budget is written on stone, you can lower the SSD to a 120GB 850EVO and/or ditch the optical drive.

Get an i5, and buy a more expensive GPU :P i7 is pointless for gaming.

It's pretty decent setup I'd say. Only thing I'd change is what Sviat above me said
Instead of i7 I'd get i5 and GTX 980 or 780 and I'd definitely change the RAM.
I can't see a reason to spend 100$ on RAM

I would add this instead: link , I am getting 200mb/s read and 212mb/s on it, fastest and cheapest Space/performance. You can just get an i5 4690K also if gaming is the main concern, no real performance difference.

The HDD is actually a rebranded hitachi hdd....so its good.

You might wanna save some money with a 290(after using 4 different brands, sapphire seems the best) also, its just as good and usually almost 100 less...and get this I would go with this PSU

Only thing i'd change is the kingston ssd to maybe a samsung evo. I've heard kingston's ssds are low-quality.

I bought that mouse/kb combo, sent it back. Keyboard doesnt like multiple keypresses at once, Think sprint, jump and take cover. It just wont register them all, and the mouse is designed horribly. After an hour or so of using it your hand will start to hurt. I know its cheap, but I'd pick something else.

the new r9 300 series look pretty solid on paper for now

If I were you I would wait a little while until the R9 series is released.

A new chip set is coming out in September so you might want to wait.
