6870/6850 crossfire questions.

post #1 of 4
Thread Starter 
Is the 6870 CF that much better than the 6850 CF?

Will I be able to max most games out on the 1GB of vram at 1080p? (I have never used AA so I will use little to no AA if necessary to get smooth frames)

Can this setup play BF3, Crysis 2 with high res textures and DX11, Crysis with mods, etc etc?

I heard that I will get low minimum framerates, is this true?

Also, would it be worth waiting it out until the 7850/70?

I've just got a second 6850 and it gives me 90-150 fps in BC2, up from 40-60 ish if it matters to you.

6870s wont really be better. From what i've seen you will get 10-15 more frames but, if you already got over 9000, who cares?

i have a 6870 crossfire setup and it definitely can play those games maxed ( not counting BF3, since its not out yet). i am however playing at 1600*900, so take my account with a grain of salt.

for BFBC2 ive gotten 100-120 fps, lowest seemed around 95 fps

crysis 2 (with mods) i have about 80 fps, sometimes goes down to 45-50 fps when there is tons of action going on (ive only seen this happen once using fraps. didnt notice any difference when i didnt have fraps)

the witcher 2 ultra specs( with ubersampling off) i have vsync on and it is always at 60 fps, sometimes goes down to 55-58 fps but thats as low as it goes.

i dont know how much more it is better then a 6850 crossfire setup is though, i cant imagine its that much different.
