hey, so i wonder when the time is right, upgrading my system a bit. so far i have been thinking to either go for one more 680, a stronger processor, a pack of 16 GB more ram, and of course i will have to buy a better psu. BUT, will it be worth it to get another 680 in say spring, or is there going to be released 780/790 in 2013? and will the rest of my system be good enough for a couple of years ? any suggestion what i should do is highly appriciated, as i have not made any decisions yet =)
