So I'm finally doing my gpu upgrade in the next 2 weeks. I've narrowed down to my two favourite choices..and this is what I've got to decide. Crossfired 7970 lightnings? or SLI 670 DCIIs? Note : the DCII's are the NON TOP edition.
I've narrowed down to these two options as they are both excellent in terms of keeping the cards cool and quiet (my reference 5850's have driven me mad with their leaf blower cooler)
From what I understand the 670 is very close to 680 performance even at stock clocks, but 670's tend to generally only be good clockers if they are models based on the 680 pcb (gigabyte WF3 for example) but i'm pretty sure the DC2 has the 680 pcb (although if someone knows for sure it'd be great to have this confirmed as the model I am looking at is the NON TOP version, yet almost all reviews only review the TOP)
In terms of the 7970s, they are the overclocking Kings this round it seems...especially the Lightning series. So then there is the 7970 vs 670 in raw performance.... the 7970's should push the higher FPS in most games from what I can see...but its all the issues I am worried about..
So, 7970 crossfire users and 670 SLI users alike, i'd love to hear from you. How are your cards going? what's going well? any games giving you a headache due to flickering or negative scaling etc?
that's another thing - negative scaling - I've experienced this a fair few times with my 4850s and 5850's...looking at benchies it seems like 7970s still have negative scaling issues here and there nowadays..but Nvidia users, have you experienced this? Don't think i've ever read about a SLI rig suffering from negative SLI scaling.
