So basically if i want a SINGLE nvidia card for a crossfire board thats ok? will i lose performance or have any compatibility issues or is it fine as long i dont try and SLI on my Crossfire board?
no performance will be lost when running an nvidia card on a crossfire compatible chipset. however, in some cases you ARE able to run SLI on a crossfire board. For example, with my DFI Infinity 975x, someone released hacked drivers which allow SLI to be run just fine.
