Hey everyone, I recently purchased an ATI 5870 cause i was able to get it for 180$. So now I am running trifire (5870 + 2X 5850(flashed to 5870s), but its shown negative improvements in most games. I ran some benchmarks on crysis, BatmanAA, Dirt2, MafiaII, Metro 2033, etc... and found that I would get a 50-100% improvement from single gpu to CF, but as soon as I ran trifire, i would lose about 5-10 fps. I get almost perfect scaling in the Heaven benchmark, and my score went way up in all 3DMarks. Now i read a lot about CPU bottleneck a while back when i only had CF, i OCd my CPU from 3.4 to 4.08 and saw improvements, but i cant push my cpu any higher. I am willing to eventually upgrade my CPU and mobo, but i havent had these cards for very long (bought the 5850s 5 months back) and would like to hang on to them for at least a year. Would a new CPU such as 1090T or any of the high end i7s help a lot?? or is it just due to the fact that trifire scales poorly? Sorry if this thread seems all over the place but im just trying to find a way to utilize trifire better.
