Still the best 7970 out there 06/10/2012
This is a review update to my initial review ("Impressed!" below).
Since that review, I sold off my XFX DD BE 7970, ran the Lightning as a single card for a while, and then purchased a second Lightning.
Currently, I am running 2 of these cards in Crossfire and it works brilliantly. Ignore the review saying that you shouldn't crossfire these. As long as you have a slot in between them and have decent case airflow (things you should ALWAYS have for a multi-GPU setup), they work great. I have mine clocked to 1205/1800 MHz on 1.21 vcore & 1.63 vram, 100% stable, with typical gaming temps in the 70s for both cards. Highest temps I've seen during any gaming was about 85C on the top card and 80C on the bottom card, which is fine for an overclocked CF setup.
This card is worth a purchase for anyone wanting a 7970 that they can overclock and not worry about it dying in a year or two, and for anyone wanting a crossfire 7970 setup @ ~1200 MHz.
OK, having had some time to work with these cards, the cons:
-In crossfire, they are loud.
-Availability and price are a big problem with these cards. You do not get a good price/performance deal at $600. In fact, it's one of the worst price/performance deals at this point in time ($600 selling price on 6-10-2012). I had to import my second card from the UK (imported for $620 shipped) because neither MSI nor newegg could get me any availability info a month ago when I needed the second card.
There's a reason AMD is notorious for bad driver support. If you don't know what you're doing with uninstalling and (re)installing your video drivers, you WILL get driver problems/BSODs/etc. Once you get a driver installed properly, there aren't many problems, but you have to know what you're doing.
Still happy with my purchase after 3 months... can't imagine running an overclocked crossfire 7970 setup with anything other than these cards.
In CF and OC'd to 1205/1800, these score about X6800-X7000 and P15800-P16500 in 3dmark11 when paired with a 4.8 GHz 2600k CPU. Very impressive stuff.
