Should I run with the MSI, Gigabyte or XFX version? Gigabyte is 20$ cheaper :P
I would personally go for the msi, i feel they run a lot cooler, and can help with Overclocking
Sapphire makes very good 7950s that overclock to 1125~ on stock voltage. Their cooler is also damn near silent.
Have the Gigabyte and its runs really Cool and Quiet
