Thanks for all the feedback, I appreciate it.
As Wint noted, I currently don't own a PS3, just s 360 and an iMac. I did play XI on the iMac (via bootcamp) for a while without problems (I switched toward the end of my XI days because of the wealth of macro options via windower, the 360 lockups in beseiged, plus being able to use ventrilo. I enjoy the 360 controller (haven't tried a PS3), so I was thinking maybe a low end gaming PC might allow me to continue using that controller along with KB and mouse as necessary. I was thinking about trying out the v2 benchmark whenever it comes out to see how my iMac might fare if I was to try it on XIV, but I am guessing it would be pretty bad as I only got a 1838 when I ran the v1 benchmark. Those are my main reasons for considering PS3 vs. PC. My max cost for a new PC is probably about what that article Wint posted said, ~$700. If I get a PS3, I could always use an old laptop with a headset for chatting.
Again, thanks for your ideas, I do appreciate them :)
