$900 rig for video editing + some gaming

[SPARTAN VI]

I got a Mac loyalist that's willing to build a PC if he can get more out of his $900 on PC. I'm not familiar with the requirements for video editing, but I do know he plans to use Adobe Premiere, which I understand takes advantage of nvidia GPUs.

1) What will you be doing with this PC? Gaming? Photoshop? Web browsing? etc
Gaming and video editing.

2) What's your budget? Are tax and shipping included?
$900 USD including tax/shipping.

3) Which country do you live in? If the U.S, please tell us the state and city if possible.
Los Angeles, California. Microcenter is nearby (35 miles)

4) What exact parts do you need for that budget? CPU, RAM, case, etc.
CPU, HSF, Mobo, RAM, HDD/SSD, GPU, PSU, Case

5) If reusing any parts, what parts will you be reusing? Please be especially specific about the power supply. List make and model.
Reusing 1920x1080@60Hz monitor, speakers, and kb/m.

6) Will you be overclocking?
Ideally no, but if the budget constraints require it, then he's open to OCing.

7) What is the max resolution of your monitor? What size is it?
1920x1080 40"

8) When do you plan on building/buying the PC?
This weekend

9) What features do you need in a motherboard? RAID? Firewire? Crossfire or SLI support? USB 3.0? SATA 6Gb/s? eSATA? Onboard video (as a backup or main GPU)? UEFI? etc.
UEFI is highly preferred.

10) Do you already have a legit and reusable/transferable OS key/license? If yes, what OS? Is it 32bit or 64bit?
Yes, Windows 10 64-bit.

Nice build.

Microcenter has the CPU for about $40 cheaper (in store pickup)

Overall, great build.

I'd recommend not getting a seagate hard drive. I've had good luck with the 2tb toshiba rebadges

This case is also on sale for 25 currently

antec platinum power supply (but rebate)

other stuff your choice but I thought i'd mention it might be worth to spend a little more to get at least the 250gb version of the ssd

also looks like the 960 in your links has a rebate

This XFX PSU is of lower quality/performance than the Seasonic you linked but it's still a good Seasonic built PSU nonetheless:
$55 - XFX TS Series 550W PSU

That'll shave off $35. Spend $10 of that on a larger SSD as it does not make financial sense to get that particular small SSD:
$80 - Crucial BX100 250GB SSD

Spend an additional $5 for this significantly better rated, reliabile, and built AsRock motherboard instead:
$73 - ASRock H97M Pro4 Intel H97 mATX Motherboard

Since we've now switched from an unreliable ATX mobo to a reliable mATX mobo, we can now use a mATX case. At $55 to $58, the NZXT Source 210 Elite is just too overpriced at that point considering that far better options aren't that much more. Since money still needs to be saved, I recommend switching from the Source 210 Elite to the Coolermaster N200 for $10 less:
$45 - Coolermaster N200 NSE-200-KKN1 mATX Case

Yes that N200 is worth the extra $20 over the Zalman case recommended earlier just based on quality alone. Tear-off expansion slots = crappy case.

If Microcenter is more than a 30 to 35 minute drive for you, then I recommend switching the CPU from the 4790 to the $35 cheaper E3-1230 V3 which that Asrock mobo apparently supports right out of the box. The performance loss is only 5% anyway:

Switch from that Seagate to a Toshiba for better reliability:
