in the end your typical computer buyer gets prebuilts so the only people buying these cards are oems and those who build their own rigs. in both cases I think they can figure it out lol. while 8 has certainly been the performance/highend for more generations 9800XT,X800XT,X1800XT,3870, 4870,5870; we did have the X1900XTX and 2900XT as well. while there was no 2800 the x1800gto was still sold alongside the x1900's being that prior to the 2900-3870 debacle the naming had been going up in number long starting with the R100 which orginally retailed as simply Radeon (either 32 or 64mb) then was rebaged as 7200 for the next launch a few months later and then again as 7000 respectively below the radeon 7500 (RV200) when it came out. then the R200 was the radeon 8500 , making 2 releases of X500 as the highend we then moved to the 9700 pro release (r300) which was the only generation to have X700 as the lead card and the X500 was moved to midrange. It was revamped under the R350 and R360 X500 and X700 removed and replaced with X800 and X600 which would stay for the next few gens (though the X700 pro was a midrange inbetween the X800pro and X600XT). R420/480, R520 and then got changed up with the R520 revamp as R580 when we got the X1900series still keeping the X1600's from the R520 lineup. the X900 and X600 naming stuck through the R600 and then changed back to X800 and X600 for the RV670/R680 lineup. this of course kept through the R700/RV770 lineup, and the current Hemlock/Cypress lineup. /long short R100 = X200 highend R200 = X500 highend R300 = X700 highend followed by X800 highend R400 = X800 highend R500 = X1800 highend followed by X1900 highend R600 = X900 highend followed by X800 highend R700 = X800 highend R800 more commonly Hemlock/Cypress = X800 highend R900 ? more commonly Antilles/Caymen = X900 highend /short the thing is going from an X800 highend to X900 highend is minor but changing gpu code names commonly used from their R numbers to their names is a bigger change and no one bitched about that. the r600 was codenamed fudo and yet we all used r600 when refering to the gpu, yet somehow no one uses rv870, they use cypress and no one uses r800, they use hemlock. to me I'd be more curious why ati is not using the generational names for radeon as much.
