I'm considering building a new PC to replace my faithful Gateway. I don't have any issues with my current PC. It actually runs fantastic and I have no complaints, but my tax return has me contemplating an upgrade. My current specs: The GFX card is a 7950 I have a 3 monitor setup currently with 2 1080p screens and a 1440x900 screen. I may upgrade to a 1440p screen and not use the 1440x900 screen anymore, so I'd like to have a graphics card that can handle that. The two builds I'm looking at: Quad core DDR3- 6 core DDR4- I'm just wondering if the difference between DDR3 and DDR4 is that big of a jump. I don't want an i5 either; I like my i7. The price differential is also irrelevant to me so long as this computer will last me as long as my current one has (almost 5 years). I'm also considering waiting for the Intel Skylake CPUs to be realeased. Thoughts?
