I have an MSI Twin Frozr R9 290 and I am aware they released more than one revision of this board.
Since my GPU upgrade is quite some time off (I am thinking March 2017) I would like to put my card under water.
In the included image is the serial number which includes V308-02SB
From memory the card has black chokes not gold ones.
What are my options for water blocks, I don't want to spend too much as it's only going to be used for another year or so.
*** Edit ***
looking at another picture of my card is V308 V1.0 just over the PCI-E Connector (pic attached)
