I'm about to buy an Asus gtx 670 and I'm wondering how much RAM to get for it. I was recently set on buying only 2GB: very few games use more than even 1GB, and even a recent review of games at 2550x1600 on this website showed that 2GB was no bottleneck. However, this has just come out....
Now, while I've no intentions whatsoever to buy this game, its 3GB memory requirement has staggered me slightly; as Battlefield 4 is a next-gen game, could this be an indication that 2GB simply isn't enough for the new consoles? (Or is it just the case that this AMD-sponsored game is cynically attempting to hook people into buying AMD's 7900 series with the announcement that you "need 3GB"? I've heard a lot of arguments from both sides.) I'm planning on using this rig for the next 3 years, at least, so it does need a certain degree of redundancy.
For reference, I'm buying the cards from here, so it's £215 for the 2GB version and £230 for the 4GB version.
