So I've got a build I've been using at work for the past 4 years. I've been slowly upgrading parts, first getting extra RAM, then putting in an SSD drive to boot from, getting a better wireless card, basic stuff like that. Now I'm really itching to get in on this 4th-gen i7 wagon, but I'd have to change out my old LGA 1156 mobo for an 1150. Everyone speaks very highly of the Z87 chipset, so I'm trying to find one that I could buy that wouldn't force me to buy new RAM. I currently have 16GB of DDR3-1333, and I can only seem to find boards that support 1600. What's the verdict, is 1333 obsolete?
