I'd be careful about simply 'averaging' performance increases in this case. Going to 266 FSB and DDR memory will improve benchmarks only to the extent that the FSB & memory bandwidth was the bottleneck. While it's not fair to focus on artificial memory bandwidth benchmarks, it is fair to focus on those applications that are hungry for more bandwidth, like quake, et. al. You'd expect virtually NO gain from artificial benches that test, say, the FPU speed (using a dataset that fits in cache). Just as you wouldn't criticize no gain in frame rate going from an 800 MHz Tbird to a 1.2 GHz Tbird in quake III on 1600 x 1200 with a crappy video card (the latter being the bottleneck), don't blame the 760 and/or DDR when you don't see a big increase in benchmarks that are largely limited by the raw CPU speed instead of data bandwidth. So, considering that the benchmarks so far have been on AMD's eval mobo (occasionally with questionable drivers), the 10-20% increases in the benchmarks that matter are actually very good. Doug

TG, improvement ... average being around the 4-8% mark That is almost exactly the improvement that AMD was claiming in this article: AMD Moves Athlon To DDR (10/27/00, 7:28 a.m. ET) By Mark Hachman, TechWeb News [...] On average, a user should experience a 3 percent to 8 percent performance increase using the new chipset and DDR memory compared with a similarly clocked Athlon, an older 200-MHz chipset, and PC133 memory, according to AMD's own tests.
