These are good cards, but MSRP is $399, so don't buy at those prices, you can find them elsewhere at MSRP prices or better.
Anyway, I purchased these cards for cryptocurrency mining, I am very happy with the results which is about 800 kh/s.
I followed directions I found online for mining settings, and made some additional tweaks in terms of AMD Catalyst control (disabled all "Overclocking" performance settings, disabled Crossfire) and these are running great without ANY overclocking! The nice thing about that is that your warranty won't be voided.
These cards are rock-solid and are very easy to setup and get going.
I'm not a gamer, but I am sure they'd be fine for that seeing as how they can be run at 100% load for over 24 hours with zero problems.
