Help Which of these is best processor.

Hi, i am looking at getting a boxx tech 3d boxx and i am looking at two different boxes. I would like to know which of three processors is the best one. Everything all other specs on workstation are similar except for processor. I am looking at Either the "Dual AMD Opteron Model 2356", or the "Dual AMD Opteron Model 2222" for the 7550 Series

I am also looking at the "Intel® Core 2 Extreme Processor QX6850" processor for the Boxx 4600 series.

Please tell me which is the best option and whether the gap between them is huge I am configuring a workstation from a manufacture with these chips as options. HELP PLEASE thanx

The Intel runs at 3.0GHz and the Opteron 2356 at 2.3GHz, so I'd expect the Intel to be roughly 30% faster.

I feel there is some additional info i must add. The Workstation that runs the intel has ddr3 memory and the one that runs the amd uses ddr2 memory.

Also For the AMD Processors the opteron 2356 is a 2.3ghz quad core and the opteron model 2222 is 3.0 ghz dual core.

For the intel it is a 3ghz quad core.

I configured everything except the processors the same and they run me at about the same price. I really don't know whether to decide on the 7550 or the 4600. From Mondoman's Post though it sounds like i should go for the 4600 the intel one.
