The boys at Anandtech have an interesting article on nForce4 Ultra motherboards
which are SLI
compatible. Yes you read that right, overall performance is not quite as
high as NF4 SLI based mobos but close! That and the boards should be cheaper
as well! =D
If you have been following the news, some very strange things are going
on with the nVidia nForce4 chipsets. About six weeks ago, MSI showed an nForce4
ULTRA motherboard with a regular x16 PCIe slot, plus an open-ended x4 PCIe slot.
Those who saw the demos said that MSI was running two matched video cards in
what they called a "semi-SLI mode", which ran at about 90% of the
performance of normal nVidia SLI. This was an interesting development because
nF4 Ultra chipsets are cheaper than nF4 SLI chipsets. The boards based on the
Ultra chipset are, therefore, much cheaper than the high-end SLI parts that
we are seeing in the market. An arrangement like this would be a god-send for
computer enthusiasts who watch their budget, yet still like to enjoy most of
the benefits of SLI dual video-card performance.
