Today NVIDIA launches their GeForce 9800 GX2 dual GPU card. It comes with two G92 GPUs and uses a new cooling design where a single cooler sits in the middle and cools both GPUs. We have the card from Zotac on our testbench today which follows the reference design specification. Unlike many other publications all our testing was conducted in Windows XP because we think that's what the majority of users still plays on.

Today we have the XFX Nforce 790i Ultra SLI Motherboard in for review and we are pairing it with a 9800 GX2 video card, also from XFX. Is this is the fastest hardware currently available? We aim to show you, in our 29 page indepth analysis.

A new desktop chipset complete with a DDR3-based memory controller is here, along with a dual-GPU powered monolith of a graphics card that is NVIDIA's most powerful to date. Together, the combination of a GeForce 9800 GX2 (or two GX2s) with the nForce 790i SLI Ultra chipset redefine the high-end of desktop PC gaming hardware.

It's been nearly two years since NVIDIA has produced a dual PCB video card design and they feel they have a winner in the works with the GeForce 9 series. One of the reasons NVIDIA feels so strongly about the GeForce 9800 GX2 is because they have a whole new approach at how the video game frames are being rendered. The first generation Quad SLI technology seen on the GeForce 7950 GX2 back in 2006, used a hybrid mode of split frame rendering (SFR) and alternate frame rendering (AFR) to enable concurrent rendering on four GPUs. With the latest games utilizing complex shaders, inter-frame effects, and multi-pass rendering, SFR becomes less efficient...

We said we would test the GX2 again once we obtained some updated drivers, and that's exactly what we're about to do right now. From a hotmail account this morning, we received the 174.51 drivers. The difference between these drivers and the last batch of 174 drivers we tried is that these ones actually installed! Word is that the new drivers fix the profile issues that were present in the 173.67 release. While some people say SLI just wasn't working in the first driver we tested, the issues seem more related to profiles.

We've all heard about the GX2, so there isn't much to say here; there's no package so we'll get stuck straight into the card and talk about its specifications before we get into the benchmarking. The main thing to compare here today is the performance of the 9800GX2 against the HD 3870 X2 from AMD. We've also thrown in the 8800GT, as the specifications on a single core of a 9800GX2 is only slightly above that of an 8800GT, this should mean that if a game doesn't take advantage of SLI then the performance should only be just above the single 8800GT.
