Raptor RAID Card on 680i Mobo

Hey All,

I have two Raptor X HDD's and I have read and heard that the 680i mobo's have RAID speed limitation issues. By limitation issues I am referring to the issue where Raptors max out at around 100 MB/s on these chipsets. I am wanting to know what RAID card I can add in to get around this issue. If there is a fix to this issue without the added cost of buying a RAID card, that would be ideal, but I have not seen anything as of yet. So if it is a Mobo issue which has been fixed in the 780i or 790i boards then it would almost be cheaper to upgrade the mobo.... You see my dilemma.

As for the RAID card what do I need to look for? Do I need the card to have RAM associated with it or can I get one with out RAM? I am not sure what it's used for. I have seen that 3Ware is pretty good, but expensive. What do you guys recommend? What other aspects do I need to look for in buying a RAID card? I need it to have 4 sata ports on it so that I can upgrade to 4 raptors in the future as well as pci-express of course.

I am not looking to start a discussion on what hard drive is better or worse than the raptor, etc. I just need some input and help on this.

Thanks in advance...
