fixed better!
where were u when i posted more info of the RV670???
Anyways, the 2950 (RV670), according to an article from theinquirer.net, it can outperform the R600:
ATI's RV670 can beat R600 - The INQUIRER
"Real purpose is to offer more than decent performance in playing the latest titles with all the details plugged to the max. If one card is not enough, AMD will support two, three and four graphics cards in a single system. The load of four RV670 boards will be less than two 2900XT boards, so the difference is striking."
RV670 clocks are not yet defined - The INQUIRER
"Prototype board with RV670XT markings, that was leaked by several vendors sported a TDP of 132 Watts, and had GPU clocked all the way to 825 MHz, with GDDR4 memory working at 1.2 GHz (2.4 GT/s), while RV670 Pro prototype came with GPU clocked at 750 MHz, and GDDR3 memory was working at 900 MHz (1.8 GT/s). This board has TDP of around 104W."
now if ur talking about the 8800GT, it can somehow have an advantage over 8800GTS but not everything. What i know myself is that the 8800GT is PCI-E 2.0 n supports a 65nm. U will need a PCI-E 2.0 mobo to test it out against an 8800GTS. The 780i mobo is coming out, it supports PCI-E 2.0. Wait for benchmarks of the 8800GT first to answer ur question is all i can say.
