I'm not sure which one I should get. Both options are going to have a water block(s) added to it and needs to be able to support 2560x1440 with HD textures. Other considerations include that I will be using the 670s in x8/x8 in comparison to the 690 running in x16.
670s:
$450 ea
4GB VRAM
2x Waterblock cost
PCIe at x8
690:
$1000
2GB VRAM
Waterblock
PCIe at x16
670s:
