@paul Thats the 4x card (I've got one!) — there's now an 8x version.

The only reason I didn't go with the HighPoint is that the drivers seem to cause a lot of grief with OS updates in forums. The Sonnet card is driverless, and fan-less.

Their products aren't the cheapest for sure, but usually there's a good reason.
