On cpubenchmark.net the 4930K is listed as more powerful than the 5930K. Can that be? On studiocat adk Haswell E setups @ 4,4 GHz are already listed. According to Scotts Benchmarks running the 5960x @ around 4,5 GHz is a massive performance gain over the 4930k. I hope stable systems are becoming soon available.
Ok I just benchmarked the i7-940: The RXC-EXT result was 91 on 256 Buffer Size.
Thank you guys so much for all the information. I know for sure now, that I will go for a Haswell E!
