Recently we brought you a showdown between ASUS' A8N SLI Deluxe and DFI's NF4 SLI-D. Today [H] check out the brother of of DFI's SLI board, the Ultra-D
The nF4 Ultra-D definitely offers some very unique and interesting features, as well as killer performance. Basically, DFI took an SLI type design and mated it with the nForce4 Ultra chipset. While this does not allow you to utilize SLI, you can use both PCI Express x16 slots for dual monitor support. The BIOS implementation is top notch, with enough voltage manipulation and memory timing settings to make even the [H]ardest enthusiast happy.
A bit of modding can get you SLI capabilities too, apparantly.
