At this point in time, I’m not sure I would spend the money to replace a 3870 with a 5770. I think if i would either get a 4870 or just wait a bit. by the time the games come out that perform better on the 5770 come you will probably have replaced it already!
[quote]When we were looking at the Radeon HD 5800 series cards, writing a conclusion was rather easy for us. We didn’t need to talk about intangibles like Eyefinity or DirectX 11, because the 5800 series brought better performance at better prices for existing games. This made recommending the 5800 series a straightforward thing to do.
But we don’t have that luxury with the Radeon HD 5700 series. The value of the 5770 in particular is clearly not going to be in its performance. Compared to AMD’s 4870, it loses well more than it wins, and if we throw out Far Cry 2, it’s around 10% slower overall. It also spends most of its time losing to NVIDIA’s GTX 260, which unfortunately the 4870 didn’t have so much trouble with. AMD clearly has put themselves in to a hole with memory bandwidth, and the 5770 doesn’t have enough of it to reach the performance it needs to be at.
If you value solely performance in today’s games, we can’t recommend the 5770. Either the 4870 1GB or the GTX 260 would be the better buy.
But don’t mistake that for a wholesale write-off of the 5770. As a 40nm product it’s cooler running and quieter than a 4870 or a GTX 260. As a DirectX 11 product it has longer legs to run on for future games and/or applications using DirectCompute 5.0. [/quote]
