Well, I believe in most cases what reviewers of a graphics card write. So I saw the reviews of the ATI Radeon HD5770 and I was excited about the stories about the low power consumption but still performance gain compared to a ATI Radeon 4850 for example. I decided to get rid of my Zotac GeForce 9800GT (AMP Edition) and bought a Sapphire 5770 Vapor-X card. What a bad surprise... this card is not worth it's price! a) I compared the results of 3DMark 2006 (1.10) ... My 9800GT reaches about 12000 points, but the new OC'ed HD5770 with 900/1320 Mhz setup was only 2000 points faster (~ 14000 points) That's what I haven't expected - such a similar result... b) I got multi monitor problems (I had never before), while using ATI overdrive, I saw a flickering screen always (even with the moderatest increase). Later I could read that's a known problem, it's related with the 2D power saving mode (and the decrease of the GPU frequency), which results exactly the flicker screen mode. Using the AMD GPU clock tool (NOT the MSI tool!) solves that, but the card is now without power saving mode if OC'ed. c) my beloved Star Wars Battlefront II was running smoothly with the old nVidia card, NO CPU load at all. NOW I got a strange behaviour with the new ATI card, almost 80-90% CPU load makes a gameplay impossible. I am convinced that's related to the Catalyst 9.12 I was using, but I have no real choice because I have to use a driver which can be used with the new 57xx series too. d) I am playing the game AION, which is based on the first FarCry (Crytek) Engine. After the change I noticed not really much more FPS, but a new phenomenon - now I have something like micro bucking/a jerky display often. And last but not least, this card costs about $ 200 ! That's ridiculous. I do not recommend this card until you're a real ATI fan without any doubt.
