I have both and I have seen no issue with rounded cables, I like the rounded cables because they do improve airflow and in crampted spaces can be a life saver (My Dimension XPS R450 case) which has a zalman HSF, Volcano HSF, 2HDD drives (1 removable), 1 optical drive, FDD, and practically every pci slot is filled with some device (either a fan control, ports or actual PCI devices). So if anyone here has seen a dell XPS R/t series case then try to image shoving all of that into that case! And none of the drives have Seriell ATA interface so thats why Round cables help in my situation.
