In case anyone was interested in the 8 port supermicro card:
http://www.newegg.com/Product/Product.aspx?Item=N82E16815121009
I did some tests on it with software raid (mdadm). So far the results were very respectful (in my opinion). Here are the results of raw sequential read/writes in raid0, raid10, raid5 and raid6 and actually performed better in software raid than a 3ware 9650se. All testing was done on a core 2 quad CPU system with the controller in a PCI-X slot hooked up to 8 seagate 750 GB 7200 RPM ES.2 series hard-drives.
Here are my results:
