Do all the Dell Precision T5600 with dual Xeon processors run slow? I purchased one and added 3 SSD drives and striped 2 480gb, ran windows 7 pro 64bit and windows 10 pro 64bit and both times my 7 year old MSI i3 runs circles around it. I have reformatted and installed windows 7 serveral times and am using the latest drives from the Asset tag. One thing irks me is that it burns CD or DVD 10 times slower than my MSI, I even swapped the two drives and still have the issue. Do I have a lemon?
