I think if you get a 6600GT, you will be VERY happy with it for all your other games for another year to come, when you can hopefully do a full upgrade.
Yup, which was my point.
And Mayor Dan is running it smoothly at 1024x768, 4x AA, with "some" shadows and lights/shaders (I'm guessing minimum level, but I'm just reading his own posts to tell!). It's certainly not FEAR in all its graphical glory, but it sounds a good bit better than what you (JM) have right now.
And, ATI's X7/800 line of cards appears to be nearly impossible to find for AGP. The X700, which was the closest to the 6600GT in performance as I recall, isn't even available for AGP. Which sucks -- it's a good bit cheaper (under $100!!).
Man, it's amazing to look at how on the ball ATI was for the Radeon 9[5-8]00 line and see how badly they fouled things up afterwards. Seems like partnering with MS for their Xbox GPU is the kiss of doom.
