Just replaced my Radeon HD5770 with NVidia GTX670 (accidentally, both of them are from Digital Alliance). Here are my impressions of GTX670:
Faster Loading Time
I was pretty surprised actually. Probably it's because the GTX670 has 256-bit interface and 2GB of memory. The HD5770 only has 1GB of memory and 128-bit interface. Can't find another reason except those two.
Smoother Animation
The micro stutter I had with HD5770 is gone now. The overall driving experience is much better. I also think it's related to the fact about how 'jittery' AMD cards are. Read the article about this 'spikey' performance of AMD cards.
Higher FPS
Well, no doubt about it. Higher core clock and wider interface helps a lot. I now can use Environment Reflection (my favorite effect in rF2) and still get smooth animation. Honestly, I think it's unfair to compare the FPS rate between HD5770 and GTX670, since they are not in the same class.
Image Quality
Surprisingly, after 30 minutes of driving and watching replays, I found no difference in terms of image quality. By the way, I don't use driver's AA and AF for both cards. All AA and AF are controlled in-game. I'm using AA Level 1, HDR on, FXAA off, and AnisoFiltering is 8x. Texture Quality Full. Screen resolution is 1600x900 32-bit.
Temperature
Using MSI After Burner, HD5770 tops at 62 degree Celsius, while GTX 670 at 73 degree. The GTX670 fan is less noisy than HD5770, even though the GTX670 Digital Alliance JetStream uses dual fans to cool the GPU. Nice.
Well, that's my first impression about GTX670. I am happy since rF2 is more fun now.
