Your suggestions have given me some food for thought for sure.
I have decided on this card:
Galaxy GeForce GTX 670 GC 1006MHZ 2GB 3004MHZ GDDR5 Dual Fan SLI 2xDVI HDMI DP PCI-E DX11 Video Card
At $350 it is a great price and offers all the advantages of a non-reference design for cooling and noise.
While I can OC a 480 to get better perfomance levels than the 670 I think for 1920x1200 I have concluded the 670 will fit the bill for me.
Thanks for all the input guys!
