I ask for help at all! Here's my story: Currently I have a Sapphire 5870, I decided to see a 470 and then pay another to do with (the same identical among others) all three reference and the original bios from ATI and Nvidia. Before all this though I had a GTX 260 and I had no problems (but I'm not sure, at time I had a different mobo and bios of the benchmark were different and no one finds more but I do not think you've had, however, cod4 and grid went well with only a slight stuttering BC2 battlefield but in Heaven 1.0 benchmark smoothly even under the 60 was ok). By 5870 I have problems and I decided long ago to 470, but testing it I discovered that he had other more serious porblem while in the games I have not had the opportunity because they had not yet come out, but still underground and crysis for both cards turned always good and continue to run well even now, although well below 60, maybe le'ffetto blur that hides the fluidity?. Back to us in the end I found that : the 5870 goes wrong with the flash video (with several, other do not know why but it seems to run well, maybe my impression) creates conflicts with the CCC and Windows 7 (especially the last 2 WHQL sti left) and with games the only way fluids is to have them do the 60 fixed by enabling vsynch otherwise I microstuttering constant and ubiquitous when it falls below 60, and I also speak of the benchmark, that heaven is the vantage 2.1 under 60 are not so fluid then runs on 50-45 -40 or below you can see it now). But WARNING the frames are there, and scores bech well, it's just too high with both frames vsynch ON or OFF must be like being in rames consistently low. I purchased the 470 and: With 470 driver 197.xxx with the original CD I had a problem, namely that when I went on the internet gave me lag and latency is too high and was unplayable in some games (just horrible) and others lose the connection every 5 min, I tried any of the games that have gone bad because now I had not left yet. Now I am made to pay another 470 the same as before and: With the 258.96 drivers if the latency is improved, however, a bad game that I first ran fine with the same vga is once ran like crap even frames fixed to 60. (Dirt, while the first two with 197.xxx was fine with a minimum of 60 frames and vsynch ON). I currently have changed: - Power supply - SSD AHCI instead of a OLD Raptor Raid 0 - I also got a sound card x-fi thinking it was the realtek issue. - RAM It remains to exclude the VGA, the cpu and mobo, the OS should be ok, but it's been one year of time someone can help me? Now I do not know what to do, the CPU how do you test? I tried LINX, memtest and prime95 blend for about 2 hours and all ok by the results and also to default was the same (even the temp ok). Flash player not so unfortunately I had to try it on Nvidia (damn!) Because I have not noticed: what the problem was not known at the time so I considered not even exist.
