Not really satisfied with 6870 CF

Hi guys,

I was hoping to get some advice, I currently have 2 x 6870 cards and to be honest, i'm not really happy with them. They make a lot of noise when playing anything remotely demanding and they struggle with games like Sleeping Dogs on 1900 by 1200 with max settings.

Is it worth me upgrading? I was thinking about selling both and then putting some cash together to buy a 7970. What do you guys think? If I can play Sleeping dogs on 1900/1200 with settings at max with no issues i'd be happy enough.

Current specs - I5 3570K (4Ghz) & 8GB RAM.

Thanks in advance
 
Lesson one in multiple GPUs. Always make sure that one card can cut it when both aren't scaling.

Also be prepared to wait for profiles and driver updates, during which time you will be a bit screwed.

Lovely cpu you got there and plenty of ram. Get a 7950 now and get another later.

For optimum performance on Sleeping Dogs at the highest settings you can't beat a 7970. A 7970 will actually run sleeping dogs better than the 'typical 5% faster than a 7950' in this game on the highest settings at 1080p because the 7970 has four extra compute units. Sleeping Dogs Extreme setting uses lots of Compute Based AA. If its not too late to reconsider, i suggest a 7970.
 
Or just using High AA :D
Extreme AA with a single card for me just wasn't playable, and two cards were a stutter fest (7970) that's my perception however. Matt iirc found max settings perfectly playable on a single card though :)

This.

You need a well clocked 7970 to even think about Extreme at 1080p. 1200 core is a minimum. You'd also want the memory up at 1719mhz (330gb of bandwidth for extreme aa) minimum. This is not taking into account the performance boost of the 12.11 and later drivers though. By the time these performance drivers had come out i had moved up in the world to 1440p. Extreme at that res was 30fps. :D I knoced AA down to HIGH and it was 45-60fps with vsync at a light overclock of 1125/1563.

Same experience I had from Crossfired 7970's with Eyefinity. Games stuttered more than Gareth gates :p
