ASUS HD 5870 Overclocks to 1035/1290 MHz on Air, Aces 3DMark Vantage in CrossFireX
Here is what four AMD Cypress GPUs can achieve with some careful overclocking, without needing any third-party cooling. Renowned overclocker Kinc sent us details of his latest achievement using four ASUS Radeon HD 5870 1 GB cards installed in a 4-way CrossFireX setup, all overclocked, and cooled by AMD's reference cooler, taking a shot at 3DMark Vantage (Extreme Preset). The four cards returned a score of X26,332 points, with an average frame-rate of 79.49 fps in GT1, and 74.83 fps in GT2.
To begin with the cards were overclocked to 1035/1290 MHz, up from reference speeds of 850/1200 MHz (core/memory). This was supported by raising the vGPU to 1.330V using GPUTool, from 1.015V. The platform to drive this feat comprised of an Intel Core i7 965 XE processor, cooled by Intel's reference (boxed) cooler, clocked at 4257 MHz. To seat them all was an ASUS P6T7 WS SuperComputer motherboard. The feat serves as a prelude to what the future holds in two "Hemlock" accelerators, which make use of two Radeon HD 5870 GPUs each.

Once you start to unleash the power of the two 8800GTS' you will see some stellar frame rates from the GX2. :)
What was the ambient temp?
Was the case closed or open?
How much of an airflow was there over the cards (e.g., a huge fan blowing right on top of those cards from an AC vent)?
Please excuse my skepticism. It's just that when there are not additional details to brag about, those details are usually not bragged about for a reason.

And in games (where it matters) scaling issues hold the 9800GX2 which is why i say it does not beat a 280.
Couple that with the fact my GX2 didn't cost me that much and I'm on for a winner either way.....there is no doubt the 280 is a solid card though. :toast:
The 4xxx series was quite a leap forward for them and a risk and it took time till they more efficiently tapped into it's power, I think the 5xxx series is mostly built on what they learned from the previous generation and and scaled/perfected so less driver pioneering will take place. We'll see.
Just an educated guess.
EDIT: Yes I know DX11 and tessellation and a few other things.. that's another story! We'll see once the games using that technology roll.
