In a typical high-end GPU launch we’ll see the process take place in phases over a couple of months if not longer. The new GPU will be launched in the form of one or two single-GPU cards, with additional cards coming to market in the following months and culminating in the launch of a dual-GPU behemoth. This is the typical process as it allows manufacturers and board partners time to increase production, stockpile chips, and work on custom designs.

But this year things aren’t so typical. GK104 wasn’t the typical high-end GPU from NVIDIA, and neither it seems is there anything typical about its launch.

NVIDIA has not been wasting any time in getting their complete GK104 based product lineup out the door. Just 6 weeks after the launch of the GeForce GTX 680, NVIDIA launched the GeForce GTX 690, their dual-GK104 monster. Now only a week after that NVIDIA is at it again, launching the GK104 based GeForce GTX 670 this morning.

Like its predecessors, GTX 670 will fill in the obligatory role as a cheaper, slower, and less power-hungry version of NVIDIA’s leading video card. This is a process that allows NVIDIA to not only put otherwise underperforming GPUs to use, but to satisfy buyers at lower price points at the same time. Throughout this entire process the trick to successfully launching any second-tier card is to try to balance performance, prices, and yields, and as we’ll see NVIDIA has managed to turn all of the knobs just right to launch a very strong product.

Back at CES 2011 EVGA showed off an interesting concept card featuring 2 GF104 GPUs on a single board. The resulting product was the EVGA GeForce GTX 460 2Win, a true dual-GPU card packing 2 GTX 460s on to a single board. EVGA has since refined this product by replacing the GTX 460s with GTX 560 Tis, and today is launching the next 2Win card: the EVGA GeForce GTX 560 Ti 2Win. Priced at $519, EVGA has the GTX 580 set in their sights, claiming to offer 30% better performance for the price. But can EVGA’s dual-GPU behemoth really surpass NVIDIA’s flagship video card? Let’s find out.

Wrapping up our two part series about NVIDIA’s new GeForce GTS 450, we have our in-depth look in to the vendor cards. As was the case with the GTX 460, NVIDIA’s partners are coming out swinging by offering a wide variety of customized cards alongside NVIDIA’s reference design. Custom PCBs, coolers, and more; you’ll find it all here.

Thus far, we’ve spent most of 2010 focusing on mainstream segments for our motherboard reviews, there’s more of that to come over the next few months starting off with a long overdue focus on AMD. Before we get to that though, there are a few loose ends to tie up on Intel’s X58 chipset – today we’re going to take a look at four motherboards aimed at the serious enthusiast.
