Believe it or not the 30fps (PS3) and 60fps(XBOX360) is quite noticeable.

After buying into the anticipation and hype of NCAA 2008 coming to the PS3, I expected to experience the same freshness, awe, and graphical bliss that I did with the first incarnation of the PS2 version of NCAA. To my dismay, I would be sorely disappointed. Sluggish is the best way to describe the PS3 experience of NCAA 2008. EA had announced a few days prior to the release that the PS3 version would come equipped with 30 frames per second, while the 360 users could experience 60 frames per second. I brushed this information off thinking I couldn't possibly distinguish the difference between 30 and 60 fps. I was completely wrong. I highly recommend skipping this incarnation of the NCAA series for PS3 and wait for the 2009 series or if you are lucky to own a 360, buy the 360 version.
