ATI Changes the X1900GT Specifications
ATI plans to change the specification of Radeon X1900GT, from 575MHz Core/1200MHz Memory to 512MHz Core/1320MHz Memory. One of the reasons is to clean up the stock for preparing the upcoming RV570 based Radeon X1950PRO in October. ATI Radeon X1900GT is based on the latest R580 core with 12 Pixel Shader Pipeline, 36 Pixel Shader Processor (ALU) and 12 ROP. In the previous specifications, the high clock speed has a duty to compensate the performance loss due to disabled Pixel Shader compared to X1900XT and XTX series of video cards. The higher clock speeds of the X1900GT, also generate high heat dissipation that lead to a noisy cooling. Perhaps, the new specification could result in less heat dissipation, and quiet operation. To compensate the performance loss due to the 11% lowered core clock speed, the memory frequency is increased by 9.1%. According AIB, both version of X1900GT would ship together, and most manufacturers would not indicate such changes.

Was trying to buy a Club3D x1900 GT for my birthday (17.9) that should have arrived in stock 14th september. Well on 14th it said 15th and on 15th they have no idea will it ever come.
Long story short, is the new x1900gt on r570 core :-o Now I propably lost you so here:

"ATI's R570 core will replace the crippled R580 cores ATI is currently using on their X1900 GT's. Along with this new core comes a new PCB."

If you look at the picture and compare it to these, you'll notice that the new x1900gt are using r570 PCB, so could it be that there are already a lot of r570 cores that can't do 600MHz or could r580 cores even work on that PCB?
Right now I'm waiting for next monday when Sapphire x1900 GT should be on stock. Really don't want those 512MHz cores, doubt they'll do that 570MHz if they are r580 ones. Just got a funny feeling when monday comes those sapphire cards will go out of stock as well and I'm waiting for ghost cards.
x1950 Pro is pushed back to month away, so that's not an option (substitute x700pro is killing me with performance, as I sold my previous card to a friend already) and don't want a 7900GS as 1280x1024 (LCD) looks *rap without AA and no point buying a SM3.0 card if you're not doing HDR.

Hope this made some sense to someone :)
