2GB vs 3GB GPU RAM

EVGA has GTX660 in either 2GB or 3GB RAM conf. and I was wondering if I should go with 3GB if I ever do a 2 monitor set-up or get a 27-inch monitor with 2560x1440 resolution down the road. Currently my monitor is 25-inch 1920x1080.

  1. 2GB is plenty for your current monitor even if you upgrade to higher res but if you get another one for extended resolution the 3GB would come in beneficial.

    Currently, only TWO GAMES (Crysis 2 and Metro 2033) uses over 2GB of vram with a triple monitor set-up.

    There is no need to go with over 2GB if you're only doing dual monitor gaming.

    And with the GTX660, it's more of a memory bandwidth issue rather than the lack of memory that usually restrains performance.

    (Only difference between GTX 660 ti and GTX 670 is that GTX 660 ti has 192 bit memory bus and GTX 670 as a 256 bit memory bus and look at the performance hit the GTX 660 ti takes when running the same games...)


    Edit: oh wait. you're looking at the GTX 660.

    Either way, that GPU isn't going to cut it gaming at higher resolutions on max settings so you don't have to worry about ever needing over 2GB of ram on it.
  3. Thanks for the info., so I guess 660 with 3GB RAM is only for triple-monitor setup I assume. Cheers.
