I built last Christmas a Kaveri APU based PC, with two 23" monitors and no external GPU. This is a PC used as a workstation for coding, image processing and the odd video transcoding. No gaming. Using stable radeon driver. The performance of this machine has really impressed me when compiling packages, but I don't have the latest generation i7 to compare it with. Unlike noisy discrete GPUs this thing is really quiet and doesn't consume much power either. The Asus MoBo has a port for an external GPU, but I don't think I will ever bother getting one - certainly not new. ;-) I have been thinking that the better compiling performance compared to my other older PCs can't just be CPU specific, it must be all these additional HSA-enabled compute cores that are doing some of the heavy lifting. I don't know how to check this though. -- Regards, Mick
