I can't decide between the Intel 2600k cpu(released) or the AMD Bulldozer cpu(releases Q2/Q3 of 2011).
I would personally wait for the bulldozer to come out in order to get a good comparison two processors. Also Price would be reduce on the sandy bridge 2600k in order to compete. So wait!!!
Since the AMD processor has not been released yet, there are no comparisons available, making a choice impossible at current, meaning that your question cannot be answered, sorry.
How will we provide evaluations whilst bulldozer hasnt been released and no benchmarks and comparisons are attainable you will merely would desire to attend till AMD launch those products to be waiting to make a nicely recommended selection on that's extra useful someplace around would or june i think of is the launch date
2600K Relatively inexpensive, beats everything out there, overclocks like crazy. Mine is running @ 4.4 ghz stable. Could take it easily up to 4.7 ghz with higher end cooling AMD core technology is far behind Intel's. Even a 2600K at stock will destroy a top end AMD 6 core CPU. I doubt that Bulldozer would even pass SB in performance
