i was thinking the same thing about the 9800's. we should watch this one closely....I mean, the 9800's are faster - but it now seems like its more due to a higher clockspeed and optimised drivers than anything else.
Yeah, I agree. Having read the 9800 mod and the improvement you are getting with it, I decided not to go for a 9800 pro 128Mb card. Like you said, the performance increase you are getting with the new drivers is big enough, add to that the clock speed increase the 9800 has over a 9700 and pretty much all you have is an overclocked 9700 with better drivers. The performance increase coming from the hardware optimizations should be really minor once you take out the clock speed increase AND the better drivers.
You know, it's good to know this stuff really because I might have ordered a 9800 pro 128mb if I didn't know where the big performance increase was coming from. Now I know. As it is, I will still be waiting for the 256mb version of the 9800 pro and see if its memory is higher clocked or not (the rumor about the DDR-II memory clocked at 460mhz on that card could still be true as we know for sure that the card will be using DDR-II memory). On the other hand, if the clock speeds on the card (especially the memory clock) end up being the same as the 128mb 9800 pros though, I will just go and buy a 9700 pro.
I am *certain* that just the extra 128mb memory on that card alone will not be justifying its price tag because 256mbs will be overkill for even Doom 3 at 1600x1200 (Carmack had said that Doom 3 would be using at about 80mbs of textures).
To me it looks like ATI really hyped up the 9800 pro because it looks like it really *is* an overclocked 9700 pro like we thought initially. For a moment, when the review sites showed that all the extra performance of the card over a 9700 pro was not coming from its clock speed alone, I had fallen for the hardware changes being responsible but now I know better.
Probably the reason ATI did this is to just fight nVidia's hype card - the dustbuster. Now I think about it, this is really lame actually. First, nVidia comes up with the NV30 which was really hyped up for months and then turns out to be a big disappointment and now the 9800 pro we all thought would be much faster than a 9700 pro is turning out to be a disappointment as well! Geee, I wonder what both ATI and nVidia have been doing all this time then??!! Right now, it looks like we should just skip both the NV AND the ATI cards that just got released and wait for the next generation stuff to really get an increase in performance. There is one good thing that comes out of all this though. The new cards, whether they suck or not, should drive the prices of the current cards down so we can buy a 9700 pro for performance or a ti4200 for great bang for the buck. I think that the ti4200's might especially sell so well now if their prices drop some.
