Hello Forum members,
 
 
I need to get some advice. I’m thinking of selling my 2 GTX 670 FTW 2gbs for some 4 gigs but not sure if it would be worth it. I game on a 1080p monitor and like to get the 60 fps. The only game right now that I see slow down with, is Crysis 3. I want some cards that will last me a few years and not sure if the 2gbs will be able to push games for the next few years.

You didn't state what you would sell the 670s for.

Before you run out of VRAM you'll run out of GPU horsepower.
Even at 1080p with all the goods turned on we're seeing games eating more than 1900MB of VRAM used.  And with time I'm sure you'll see games eating up to 2GB + this and next year.  However the 670 doesn't have the grunt.
 
Recommendation, get a 7950/7970/7990 however realize that even with the amazing drivers that AMD has been pushing out their CrossFire support is still slow vs Nvidia's SLI profile, if you go with dual cards.
The Nvidia upgrade path would be 4GB 680 in SLI or single/two Titans (a single Titan isn't a "true" upgrade for you, however Titan does have more GPU grunt just won't give you high high FPS).

Unless your running a game like skyrim with a crap ton of mods 2GB is fine for 1080p. I would only say grab the 4GB cards if you ever plan on going multiple monitors, hires or 3D.
