You may get the same or better performance but the increased power consumption/heat /lack of upgrade option makes the single card a better choice.


also Lower end cards also tend not to do as well in multi-card configurations

Personally, i think 2 7770 will blow away a 560ti.

actually 2 7770's is 7950 performance so yes you'll be better then one 560Ti it would take 1 1/2 560 Ti's to beat 7770 Crossfire.

my 7770 is about 3% better then a 6870 due to the driver performance boosts and the overclock i got and 6870 and 560TI do share blows unless physx is used or massive amount of tessellation then the 6870 gets hit hard but my 7770 still pulls ahead slightly.. so i could probably share blows with the 560TI.

correction for you.
It will be confusing for the OP/threadstarter to read your reply.
He might actually think a stock 7770 can beat a stock 6870.

No no I think iam able to follow you guys lol, seeing that its overclocked it will come ahead slightly correct? The 7770 is going for 130 with tax so I was commparing that's all. Will I be able to play games on medium settings with 1 7770? That is until iamm able to get another one for crossfire if I had the extra money id go for a 670 or 680 but times are tuff so u gotta stretch that dollar lol

well at stock it'll perform as the 6850 stock but when the 7770 is overclocked to around 1200mhz it'll hit 6870 speeds with current driver improvements smile.gif

7770 for 130 is a great deal, medium settings on most games can play BF3 around the medium to high area at 1080p but if you got 1440x900 res like i do then you can go high detail settings and get great fps which for me i'm getting 40+ never dipping below 40.. smile.gif

in terms of the 670 and 680 the 670 would provide better bang for the buck as the 670 is 5% or so slower then the 680 in turns a slight OC to the 670 and it'll perform as much as a 680 smile.gif

i agree have to stretch it as far as it can go now a days. smile.gif also to 2 7770's got scaling just like the 6850/70 of nearly 100% or more than 100% in games that utilize crossfire or SLI well biggrin.gif

not just medium settings lol.
a single HD7770 can max out most of the games already.
Metro2033 and Crysis 2 are the few games that cant be maxed out.
You will still enjoy them though, because you can run high settings without lag


Crossfiring HD7770 is probably not a good idea because it only has 1GB vram.
You will get HD7950 speeds but will run out of ram on higher resolutions.

BF3 can't be maxed ethier biggrin.gif, 7770 Crossfire at 1080 let alone 1680x1050 is a sweetspot fo these cards but they do provide great power in multi monitors solutions they're like the 6870 in a way they got alot of power but that 1gb limit runs out before the horsepower does also to depends on the resolution like for example 1366x768 x 3 would do the 1gb envelope with minor performance hits compared to 1080p x 3 or higher which would be higher impact in performance biggrin.gif
