Thanks for the advice!
Although that is a good card, it doesn't fit my criteria of being silent, since it has a fan. Plus, I am uncertain as to whether it can be used on a 1.0a PCI-express buss. It is my understanding that 2.0 can be used on 1.0a but I have been told that 2.1 and up are not compatible?? Please correct me if I am wrong on that!
