New graphics card

(1/3) > >>

ckaack:
I am considering to upgrade from GeForce 465 to a Geforce 570 or Radeon 6970. The benchmarked FPS of a GeForce 570 are a bit higher than the Radeon 6970, but the Radeon 6970 has 2GB RAM instead of 1.2GB. I am not sure whether the larger memory will support FSX better. Has anyone any experiance?

meshman:
In simple terms, it's not how much memory, but how fast you can het to it. The ATi/AMD cards have a limitation of 256-bit data channel, whereas the 570 uses a 320-bit channel. I'll take the faster transfer ability over more memory.

It also depends if the rest of your computer is fast enough to feed the data to the video card?

Frank Lindberg:
Any card over 800 MB won't be a problem for FSX.. More importing is your CPU and RAM  ;) and of course your choice of OS, it must be something like WIN7-64 bit.

feer:
hi, ckaack frank is right any card over 800mb in fsx is the way to go is nvidia much beter any way you have a good card too regards feer.. ;)

ckaack:
I do have an i7920 @3GHz water cooled on an Asus Sabertooth X58. My current GeForce GTX465 passed away for whatever reason and therefore I do require a new card. Your explanation of the broader memory access does make sense to me and will follow your advice of procuring a GeForce GTX570.
