No issues here. Playing Diablo 3 with Adaptive MSAA @ 4xHQ, and things look good.

Weird... I can't force MSAA within D3 yet, using both the 12.7 beta suite and the 12.7 CAPs. That's following a complete removal and reinstallation to try and resolve the video-corrupting-the-primary-display issue I've been having (didn't help that, either).

Only the internal AA setting seems to have any effect for me. That includes all three AA modes and trying MLAA (which should have worked anyway).

Ed: I stand corrected. It does work, but only in fullscreen mode. Neither windowed nor fullscreen windowed see any benefit from it. How bizarre...

Alright found someone selling a 7970 Direct CU for $450 s/h. Think it's worth it? If it is I guess I'll have to bet a bigger PSU and mobo

Give me access to these bloody shop forums here

Theres a nice deal at Amazon for an MSI 7950 Twin Frozr. $340 plus $15 to ship to Aus. Theres a $20 mail in rebate as well. But thats only for US residents.

Runs fairly cool so it has quite a bit of overclocking headroom and the price isn't bad at all.

Talking about Ghz editions; when are we supposed to be seeing these mythical beasts?

AMD's flagship Southern Islands dual-GPU graphics card, Radeon HD 7990, is set to launch in the second half of July, according to various reports. Sporting two Tahiti-XT GPUs, there will be a total of 4096 GCN cores, along with 256 TMU and 64 ROPs, as well as 6 GB of GDDR5 memory for the reference design.
Although clock speeds are not yet confirmed, previous rumors have suggested it will have a core speed of 850 MHz and a memory speed of 1250 MHz (5000 MHz effective). What is known is that the cards will support AMDs new Turbo feature. How this will compare to NVidia's dual-GPU Kepler card, GeForce GTX 690, is not yet known.

The 7990 is rumoured to launch late July, But it looks like it will have a core clock of 850mhz , It won't be the 690-killer that AMD needs.

But it won't cost $1600 and should be actually available in quantity.

lol you got that one right

[bobbavet]

Meh... I've given up on the 7990.

THey can't even arrange any design / specification slide leaks for the hype machine.

It's a deadduck. Looks like a 2nd GTX680 for me. Unless released at same price.

Sorry to knock you's off topic (1st post so don't hurt me lol jokes)

I need some advice from this awesome community on a GPU upgrade to my new system, the 6970's came from my old system along with the power supply however the power supply has gone faulty and destroyed one of the 2 GPU's.

So I'm looking for at what's around and could do with suggestions on really good cards (to last years at awesome graphics settings).
Not sure if ATI or nvidea is better for performance nowdays,
(I believe the motherboard can support crossfire and SLI, posting here as currently leaning the ati way as i haven't used a nvidea card since the pentium days lol so no idea what there like atm)
The system its going in:
Motherboard: Asus rampage extreme iv
ram: 32GB
CPU: Intel® Core™ i7-3930K CPU @3.2GHz
Case: Coolermaster stormtrooper

I'm looking at maybe 2 cards like before for abit more power. Got a replacement 1500wat power supply on order to power them.
If it helps, I'm a person who loves to max out every graphics setting his system will handle.

Thanks in advance for any help,

Currently mainly looked at: (but undecided)
ASUS Radeon HD7970 DirectCU II TOP 3GB http://www.pccasegear.com/index.php?...ducts_id=19553
and
Sapphire Radeon HD7970 3GB OC
http://www.pccasegear.com/index.php?...ducts_id=19742

not sure how well ventilation will work with 2 x the asus one, as it will only have 1 (empty) pci slot between the cards. (possibly defeating whatever extra cooling it gets from being so massive, well at least for the top card)
