MSI 7970 OC vs. Gigabyte 7970 Ghz Edition

I have been searching for a good video card for my first build and finally decided to get a 7970. Now I have narrowed it down to two cards:

MSI:

Gigabyte:

I would like to know which of these cards would perform best at 1920x1080. Feel free to ask me any other questions and make other suggestions. Any insight is appreciated!
