Been looking at the prices already, dropping fast. I might pick up a 5600 Ultra anyways. The 128mb 5200s are under $90 already.
It appears the 5600s have a higher RAMDAC, 400 compared to the 5200's 350. Since my use is primarily HTPC, with dual monitors (second HDTV), the higher the better. I've been really dissapointed with the 8500 I have. The DVI/VGA port over the past year has become unusable, and I had to shift my HDTV to the VGA port. On the DVI port I have flickering lines, which is driving me nuts even as we speak.
