My 8x2.8ghz is getting old. Not really impressed with what apple offers right now and I mostly run Windows on it anyway so I was considering gettting a PC. How would a i7-980 with some watercooling and clocking perform compared to it? This one: Intel® Core™ i7-980 Processor Socket-LGA1366, Six Core, 3.33Ghz, 12MB, 130W, QPI: 4,8GT/sec Also is the 2600k better? How would it compare?
