Hi, I'm very confused now since I decided to go for PC (vs Mac) for DAW work I don't understand what the problem is regarding PCIe. I gather it is a bandwidth issue, but is USB also affected (Mbox, ect.)? :shock: Also, are the reports true that HP AMD64 laptops feature video+firewire+pci all on the same bus (so same problem)? I am looking to use the machine almost exclusively for VST (Reaktor, Absynth)+MIDI work in Live 4 which I would output to PA or secondary DAW. For this does PCIe/bus-speed even matter? I would go for a Dell 9300 for its Dorthan(1.7)/gpu which I have heard the L2 cache really shines with, or an HP zv5000z w/ AMD64-3700. I have read the posting by the Alienware owner though and am a bit weary, advice would be truly appreciated!! :?
