Debating on getting a single 5770 or throwing in another 4670 and running crossfire with 2 gigs total ram (from the gc, not the mobo it has 4 gigs gskill 1066 ddr2) ddr3 clocked at 1800 mhz with a 128 bit bandwidth. The 5770 I'm looking at is a sapphire with a gig of gddr5 running a mem clock of 1200 mhz I found on new egg. Anyone ran either or both rigs? I'm running on a Kuma 7850+ black edition processor oc'ed to 3.2 ghz. I'm not trying to brag, but I don't know if this makes a difference with dx11, and besides it's only dual core anyway I want to throw in a phenom but need the cash first. Anyway, I have ADD to the MAX. Advice on the cards?
More aboutdual 4670 versus single 5770
Hello... Welcome to the forums...
Well, dual 4670 is about the same performance with a single 4850. And 5770 is about the same performance with 4870 minus dx.11
U will be better with 5770...
Thanks man. I'm thinking I'll just wait until I can cough up the extra fifty and get the better card. Then maybe when they go down run those in crossfire for next generation or later games until they drop.
Single card, newest generation > crossfire, 1 generation older, 1 tier lower. notice that the 3rd digit of 5770 is 7, which is higher than the 6 of the 4670. That means that if alone, even a x7xx card of the same generation (ie: a 4770 or 4750) will beat the 4670. Add the fact that the 5770 is newer by a generation, then it means that the 5770 will beat the older generation equivalent, which is the 4770.
tl;dr: 5770 > 2 x 4650, because 5770 is newer generation, has lower power consumption, and doesn't have multi-gpu scaling issues.
