I'm still doing research into my next computer purchase. I see that\nthe Studio 8000 has a model number change to the 8100. I'm looking for\ndifferences between the two XPS Studios.\n\nThe 8100 starts at 9. The 9000 starts at 9.\n\nThe main difference as I see it, is the processor.\nThe 8100 comes with the Intel Core i5-650.\nThe 9000 comes with the Intel Core i7-920.\n\nMemory\n8100 has up to 16 GB dual channel.\n9000 has up to 24 GB tri-channel.\n\nExpandability\n8100 has ?? hard drive bays\n9000 has 3 hard drive bays\n\nPower Supply\n8100 has ?? watt supply\n9000 has a 475 watt supply\n\nWhat else am I missing?
