Summary: This is a good card for the money, but if you are going to get something more powerful than a 2600k, such as a 3770k or higher, then you should get a better card--this one will be the bottle neck for more powerful systems. Very stable, but problems with new drivers. Overall a good card if you have an older system and want to upgrade just the card.
Summary: I can't recommend that you purchase this card these days, as it's skyrocketed in price since I bought it and there are better, less expensive cards out there. It does the trick for me, and it's still a smoking card if you can find it under $200.
Summary: Bought to replace a 8800GT display card on a gaming machine, specifically for running Planetside 2. The boost in performance was more than double - I can run PS2, a very heavy, GPU and CPU intensive game, on high settings or medium settings and get excellent performance (75+ fps). When things get intense (300+ people fighting in the same area), fps begins to drop but never below ~45).
Summary: I upgraded from an awful out of date gtx 295 with a xeno killer chip. So far I've only had one hiccup with this product which is that it will crash sometimes and then quickly recover and I will get a message saying that the card has crashed and recovered, but it usually happens when I'm not doing anything other than surfing the web?
Summary: The last game I played was Counter Strike on a terrible GPU at 30 frames a second. My last "high-end" GPU was a 9500GT that was never used for games. I heard about BF3 and was sold after seeing the trailer. I bought this card, and a G500 mouse, all for BF3. WOW! The card is great, the details are amazing. I am getting around 60FPS on 4 gigs of ram and q9550, running win7 64bit at High settings (not oc'ed).
