Rodson :
What is the difference between the MSI GTX 970 Twin Frozr and the MSI GTX 4GD5T?
GPU clock speeds are higher on the Twin Frozr V model.
The Twin Frozr V model requires one 75-Watt 6-pin and one 150-Watt 8-pin PCI-Express power connectors whereas the 4GD5T only requires two 75 Watt 6-pin PCI Express supplementary power connectors.
The Twin Frozr V model uses a better cooler.
