ATI 6870

[ithrial]

Just an FYI, my Sapphire 6870 will be here hopefully in the next couple of days. Replaced my GTX 275 as the 260 SLI surround drivers suck. Will be testing Crysis, Dawn of War II, WoW, Dragon Age: Origins, CoD MW1 (and Black Ops when it comes out), Company of Heroes and Blacklight Tango. Any other requests that I might get my hands on?

Just Cause 2, if you've got it?

Im sure I can get my hands on a copy

I went looking on Amazon.com to see how much it was in the States, as on Amazon.co.uk, last time I checked, it was £8 or something crazy like that. $38. Ouch.

Got my card in yesterday - ran the 3DMark06 - that one card beat out my 2 GTx 275s - also has a higher windows 7 rating. Bad thing is that I didnt think I was gonna need a DP adapter so I didnt get one. Then I went to best buy and picked up one of the apple Mini-DP to DVI passive - no go their either. Even though there are 4 separate clocks (DL-DVI/HDMI, SL-DVI, DP,DP) you still have to have that extra power to even use the DP extended - so Accell got my $36 last night and i'll be getting a mini-DP to SL-DVI active display, good thing I only have 19" monitors. As soon as I get that in, I will be testing if I can mix and match my 6870 with my 9800GT for another monitor and PhysX.

WoW = amazing FPS even in dalara
Bioshock = Amazing
Oblivion - amazin
Hawx 2 Benchmark @ 3840x1024 + bezel adjustments - all settings high with x4 AA and Direct X 11 TT - avg 58 fps with max @ 78
Dragon Age Origins - looks great - converstation options were in the middle of the bezels though so that was annoying

more tests to come

Not sure what you mean there, but fundamentally, in terms of the display clock sources HD 6000 is the same as HD 5000; there are two sources for legacy devices and one source for DP (which can be shared accross multiple DP outputs).

Does the HD 6000 support bezel compensation with different brands of monitors at the same resolution?

Were you running in Ultra settings in Dalaran ?

I'm currently running a Sapphire 5850 1Gb Toxic, and considering a 6870 Crossfire setup. To buy the same 5850 to Crossfire now, the cards are still expensive ($400) compared to the shiny new price point of the 6870 ($300 each). I am just finding that the 5850 is being pushed to it's limits in 3:1 Eyefinity (6080x1080 bezel compensated), and wondering if anyone knows if WoW actually benefits in performance from a Crossfire 6870 setup. The "official" Blizzard line is "WoW supports Crossfire, but that doesn't necessarily mean you will see a performance increase" which is slightly disconcerting.

Any suggestions or thoughts would be most welcome.

Wow for the most part is cpu rendered. I know that will change somewhat in cataclysm. So really, you wont see a performance bump now, but later? Maybe.

"The card has two DVI ports, two mini- DisplayPort and one HDMI port. AMD's display output logic is clearly superior to what NVIDIA has to offer at this time. Vendors are free to combine six TMDS links into any output configuration they want (dual-link DVI consuming two links) - and use them all at the same time. AMD has also introduced DisplayPort 1.2 support with their new cards which allows the use of a DisplayPort hub to connect multiple monitors, or daisy chain them together. "

(same words for 6850 just one display port not two mini-display port

iirc 5*** series had 4 clock sources ,now you are telling 68** series has 4 clock sources not 6 ,correct?

[ithrial]

6 if you do dual min-DP monitors or daisy chaining or if you get 2 of those mini-dp to 3 dvi display ups (dell has em for about $180)

I was misunderstanding what clocks meant when i wrote about em - thought that the clocks for DP were different than DVI and the HDMI

Yes it supports Bezel correction - but thats built into the driver and not the card.

Im not sure what kind of configurations you can mix and match using the display ports and DVI/HDMI (since the DL-DVI , SL-DVI and HDMI share 2 clocks) but my guess would be any mix of 6 with the exception of using both DVIs and the HDMI

Yes I was running in Ultra in Dalara, but WoW is very CPU intensive - thats why I have my CPU OC'd - that and my hearth isnt the main inn by the south bank - I hearth to the sewers where its less crowded
