Right now i have a 5770 Xfire setup. i need to upgrade and i am thinking of either getting two 6870's to crossfire, or to 7770's to crossfire. But it seems the 7770's are close to the 5770 in performance and i'm not sure what would yield better FPS in games.
so basically, should i stay with what i have(Xfire 5770's), go for 2 6870's, or go with 2 7770's
I'd go 2x 6870's, personally, I'd pick up the 2GB versions if I was going to crossfire that way you're not bottlnecked by your VRAM at high resolutions.
They'd do the trick, I was just suggesting what I'd personally do if I was considering crossfire. Those would work just fine.
unless you are running more than a monitor 1 GB will do fine
I recommended crossfire 2GB's not only for present games, but it would give overhead for a couple years to come and will be better long term investment. Majority of games now for 1080 resolution and below are fine with 1GB, but there are games that indeed to use more than 1GB even at 1080 on a single monitor. 1GB is just fine, I was suggesting the ideal option when considering crossfiring 6870's, however a year or two down the line, 2GB versions may be hard to find if you ever have a problem with one of the cards.
