new GPU

[bn880]

yes, all m chips on both AMD and NVIDIA are lower spec desktop chips tweaked to meet the lower TDP. However 7970m was not a mobile rebadge. It is the latest gen new card/chip. (meant to compete with 680m which was also not a mobile rebadge, unlike 670m)

Go with Nvidia. I have a 7970 (second one) and have had nothing but problems.

I run 3 monitors in sli sometimes for pure eye pleasure and frame smoothness, and would leave it on sli all the time except for; cant run additional screens for pit. So most of the time I want the pit, which is sort of the pits for eye pleasure, He He.The 3 monitors are connected to a single display port on GPU using a matrox th2go . This is a limitation to sli but it still works in my opinion, Mark.

AMD X-FIRE & QUAD-FIRE works (kinda)

 

I have been running 2 6990's quadfire for the last 1 1/2yrs. AMD drivers support is Terrible !! (DCS) It will run game on all 4 cores but never use more than 30% of the GPU's and same on CPU cores. FPS in game are 15-45... Same driver pckage runs other games at 60-90%. with FPS's to match. But a diff driver package could and has cut perfomance in half... Folding@Home perfect example,, on 1 driver it will run all 4 cores at 90+ %,,a diff, 1 it only runs at 30% on the 4 cores.etc.etc.

Do not buy a dual core AMD Graphics card. Save yourself the headaches,, get the best single core AMD or Nvidea....Game not optimized for multiple CPU's let alone GPU's.. Game is DX9 so the demands are diff than the DX11

And AMD only supporting most popular games.

Possibly thinking about buying a 680 to replace my 580, the benchmarks that i have seen suggest that it might be a worthwhile upgrade ????.

 

However i'm intrigued by the fact that some of you guys have said that SLI is working for Nvidia in DCS.

 

Would it be possible to SLI my 580 with a new 680 ?, never tried SLI before so i don't have any experience of it. My 580 is a good card and works well so in some ways i'm a little reluctant to retire it just yet...

change the XFire profile to a different program.

Update Cat 13.1 Killed performance in several games for me. Foldinging@Home chugged along at 30% usage.. But not surprisingly gave me Good benchmarks w/Heaven DX11,,only a few pts. and 10FPS"s behind the Cat 12.3 driver package.. Oh and as a side note, going thru the same uninstal proces as I have done 200 times if I've done it twice.. The UNINSTALER, uninstalled the Raid driver, leaving me,,unable to boot (3 ssd"s in a stripe),,,thank AMD....simple fix,(if you have thumb drive handy,,internet access and know which specific drivers you need) but still no excuse for that.. Hopefully this makes decision about graphics card purchase easier..

or you do the custom uninstall and select graphics drivers and leave AMD Chipset and Raid drivers unchecked.
