I just got my hands on 2nd grafic but something is wrong. I get good score at benchmark and furmark but in games its total bulls..t. Here is one ex Skyrim everything on ultra running about 60 fps with a single card, while with sli activated it runs few fps lower *Frustrating*.
Same goes for BF3 ...
.Corsair TX 750W V2 /80+ Bronze
.MK Gigabyte GA-Z77X-UD3H Socket 1155,
.CPU Core i5 3570K 3,4Ghz
.Crucial Ballistix Sport 1600MHz 2x4GB
.Crucial SSD 128 GB m4
.2x EVGA GF GTX 670 Super OC 4GB *
.HD1TB Seagate SATA 6Gb/s 64MB
.SAmsung 120 hz monitor 1920x1080
And yes i have tried new drivers and old ones >S.
Both cards works good as a single one , tested.
After some tests i run.One of the card got 2100 score heaven benchmark, but the one got 2800. In additon to that one card is hotter than the other like 5 temp or 8. I will try to do some more test...
Bf3 on ultra settings: highest fps is 130+, the lowest can be around 65 60. So sli works in Bf3 for sure.But I thought i wouldnt go down to 90 fps with sli which is very disappointing.
I didnt clock my cpu yet. But something else happened when i came home from my trip, i got black screen when i started up windows.
I was afraid that one of my cards are defected, so i put out each one but they worked perfectly as a single one.
I made clean install of drivers, rebooted pc, after that i put back my 2nd card in slot.
Well now i feel kinda stupid but that fixed all the fps issues in bf3. now i drop to 85=90 fps when i see some hardcore action other wise its 110-120 +++ fps.
Thank you people for all reply's. Im off to play some bf3 >D
