Im thinking about purchasing this V-card for my system though i see on neweggs site they have a 64mb and 128mb versions. and a $26 Difference. Will there be any substantial difference in performance in games using the 128mb over 64mb? Is the 128mb only necessary if you plan on using Hi-res to play the games? Would like some input if its good to spend the xtra money or not... I dont plan on plying on a very high-res due to monitor, any other advantages?
