Soldato
If Nvidia feel they are loosing lots of sales to AMD by people who have a freesync monitor then yes. However, as it stands Nvidia are still maintaining nearly 80% of the discrete desktop GPU sales so there is no sign of many fresync owner really swinging the sales stats.
Something similar happens back in the chipsets days when only where chipsets where supporting SLI, the 680i/780i where both relatively pap next to Intel's offerings on the high end, sales dropped and they got out of the chipset business for better or worse.
End result SLI was licence for non nvidia chipsets finally.

I still kinds long for the days when there was more than the CPU vendor supplying chipset for there CPU's, I grew up with the likes of SiS, VIA making chipsets. At one point in the Athlon 64 days we had SIS, VIA, AMD/ATI and Nvidia making chipsets for the platform.
