This is my first time attempting to build a custom pc.. I have an idea of what I want but need help choosing the best components. My budget is around 1200 dollars.. All I have right now is the antec twelve hundred v3 case..... and a kdmpower 750W Gaming 140MM Blue LED Fan Guard Grill Silent ATX Power Supply PSU 12V......I was thinking of getting the following.... ((Intel Core i5-4670K Quad-Core Desktop Processor)) .......((Western Digital Caviar Black 2 TB SATA III 7200 RPM 64 MB Cache Bulk/OEM Internal Desktop Hard Drive - WD2002FAEX)).........((ASUS MAXIMUS VI HERO DDR3 2800 LGA 1150 Motherboard socket for 4th Generation Intel Core i7/ i5/ i3/ Pentium / Celeron Processors))......... ((EVGA GeForce GTX760 SuperClocked w/EVGA ACX Cooler 2GB GDDR5 256bit, Dual-Link DVI-I, DVI-D, HDMI,DP, SLI Ready Graphics Card (02G-P4-2765-KR) Graphics Cards))......((Corsair Vengeance 16GB (2x8GB) DDR3 1600 MHz (PC3 12800) Desktop Memory (CMZ16GX3M2A1600C10))...I'm not positive if all of this is compatible...and if it would be better I am willing to buy a new PSU. ..I eventually want a watercooling system as well but unsure on which to get...and I also want to buy windows 8.1 for this pc!.. This will be for mainly gaming....and music download./video editting......any advice is greatly appreciated!!
