what is the understanding of "performing"? ...but u can easly compare on
http://www.futuremark.com/hardware/cpu#, by adding a virtual pc wich fits ur components. it will perform very well. No amd (no matter wich price), is available yet, wich could even reach this performance. together with a raid0 (ssd) u have nearly the fastes desktop solution available for "mortal" human on planet earth.
really dumb question: right now this is happening when im encoding. How much faster would be the i7-4820 be?
