Which one should I get? If i do mostly just gaming and rendering vids. This is my current system: Intel Core i7 950(3.06GHz) 64 bit Quad-Core Processor Asus Sabertooth X58 Motherboard 12GB RAM (6x2GB) DDR3 1333 1TB (1 x 1TB) SATA-III 6.0Gb/s 7200RPM HDD 2TB 64MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive GeForce GTX 680 2GB 750W PSU 120mm Liquid Cooling System
I would go with the 3930k ... Its going to run you more money ... it benchmarks higher and doesnt have the ivy bridge overclocking problems.
I second that, but if you want to save yourself some money with out much of a performance drop, think about the i7 - 2600K,
