erm mitrank you need to decide the graphic card acc to your monitor and vice verca.
i am not sure if 5670 can handle a 23".
68xx series replaces 57xx series 56xx series is to be replaced by 67xx series. thats why 6850 is double 5670.
not double.more than 2.5times
Well the XFX 5670 costs Rs 5600 and XFX 6850 should cost Rs 12000 , so about double , 2.5 times would be Rs 14000 , i could get the 6870 at that price.
Well that's not my point , what i have to decide is whether i am going to play games . For gaming at atleast a decent resolution for a 23" Monitor , i do need the 6850, but that wouldn't matter if i don;t play games at all. Also , 6850 is newly launched, its quite high priced and won;t come down until 470/560 is launched. 5670 is sellling at a very good price for its performance.
any new rumors on 69xx?..today is 12.12
ps: if you regularly use MATLAB, you might look into buying nvidia cards as the CUDA is supported by MATLAB and will accelerate performance if used.
