Jaguar...you might want to rethink the MOBO you are getting with the 7800, from one of the reviews on MSI for that mobo, is does not support the 7800 SLI
DONT BUY THIS 'SLI' BOARD
http://forum.msi.com.tw/index.php?topic=82427.0 Very disapointed to find after the fact that SLI 7800 cards wont fit. Very bad move on MSI's part. This board is useless without the option to upgrade to the latest cards in SLI. Raw deal indeed, see link for more info.
hope this help before you purchase the Mobo...id keep the VC and just look for another mobo...Gigabyte if i may suggest
