My son has picked out a list of items to build his own gaming PC. What are your thoughts, opinions, suggestions, etc.? AMD FX 4100 4-Core Processor, 3.6 4 Socket AM3+ FD4100WMGUSBX Corsair CX750 Builder Series ATX 80 PLUS Bronze Certified Power Supply Gigabyte AMD 760G + SB710 Chipset DDR3 1333 AM3+ Micro ATX Motherboard (GA-78LMT- S2P) Corsair Vengeance 16GB (2x8GB) DDR3 1600 MHz (PC3 12800) Desktop Memory (CMZ16GX3M2A1600C10) NZXT Guardian Black SECC Steel Chassis ATX Mid Tower Case 921RB-BL I remember seeing an awesome build guide on here years ago, but can't find anything up to date. He has around $400 to spend, but if you go over that cost with your feedback it's understandable. He wants something to play games like Call of Duty and other hi res games. Any help is greatly appreciated!
