So I'm looking to get a new computer. My budget is $1300, using the computer for vidya and video editing.

Processor (CPU) Intel® Core™i7 Quad Core Processor i7-6700k (4.0GHz) 8MB Cache

Motherboard ASUS® Z170-P: ATX, LG1151

Memory (RAM) 16GB Corsair Vengeance DDR4 3000MHz X.M.P (2 x 8GB)

Graphics Card 4GB NVIDIA GEFORCE GTX 960

120GB SAMSUNG 650 2.5" SSD, SATA 6Gb/s (upto 540MB/sR | 450MB/sW)

1TB SATA-III 3.5" HDD, 6GB/s, 7200RPM, 32MB CACHE

Power Supply CORSAIR 550W VS SERIES™ VS-550 POWER SUPPLY

Super Quiet Titan DragonFly Heatpipe Intel CPU Cooler

Thermal Paste (ARCTIC MX-4 EXTREME THERMAL CONDUCTIVITY COMPOUND)

Any ideas on how to either improve the build with the same or less, or anything to decrease the cost with minimal impact to performance?
