I'm currently using a AMD Phenom II X6 1100T w/ 16GB's GSkill F3-12800 DDR3 memory and a Nvidia GTX 550Ti using a heavy mix of PP and AE. System seems to crawl for what I'm doing so will be upgrading what I can afford right now.
I will be upgrading to a Haswell I7-4700k. If I only had around $300 more to spend would it be better to get 32GB's of RAM or a better graphics card?
Make that an i7-4770K and 32 GB of RAM.
I'd go for the RAM myself.
