1. use a i5 3570k.
2. don't use SSD for recording gameplay- HDD has enough throughput for that. Actually, just record gameplay to the 1TB drive.
3. just use 8GB of RAM.
that should save you a couple hundred without affecting gameplay or streaming at all. the 3770k *might* be a tiny bit faster for encoding videos or something really processor intensive (games aren't usually that CPU intensive)
