I've put together a build on the partpicker website:
Intel Core i7-4770K, Sapphire Radeon HD 7970 GHz Edition, Cooler Master HAF 912 - System Build - PCPartPicker
CPU: Intel Core i7-4770K 3.5GHz Quad-Core Processor
Motherboard: Asus Z87-PRO ATX LGA1150 Motherboard
Memory: Corsair Vengeance 16GB (4 x 4GB) DDR3-1600 Memory
HD: Samsung 840 Series 250GB 2.5" Solid State Disk
HD2: Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive
Video Card: Sapphire Radeon HD 7970 GHz Edition 3GB Video Card
Case: Cooler Master HAF 912 ATX Mid Tower Case
Power Supply: Corsair Enthusiast 850W 80 PLUS Bronze Certified ATX12V / EPS12V Power Supply
In addition to the above i'm also getting a generic optical drive and I have 2 HD's from my old computer that i will be installing.
My budget is $1500 and i'd like to build a mid to high performance PC for gaming and video editing. I'd like some feedback on this combination of parts - I'm not totally new to this but the last PC i built myself was about 8 years ago so I am out of practice. What i'm unsure about is if the Sapphire 7970 card is the right option and whether my Case & Power supply will support everything i'm trying to throw in.
I would also appreciate some tips on peripherals (Screws, Cables, Fans etc) that I should also order along with the components.
