ATI is not newbie friendly. And I agree with you, OP, the CCC drivers are a pile of crap. They do have capability, and currently ATI hardware > Nvidia hardware. However, the grey-screen crash, 2nd monitor flickering, and powerplay bugs are absolutely real issues that ATI doesn't seem to bother putting effort into repairing.
If you want the best user-friendly experience, I agree, toss in a stock GTX285, load up the drivers & basic NVCP and begin your Batman save and enjoy good framerates & Phys-X. Something anyone kid or grandma with a BB gift card could do.
If you want top of the line hardware, benchmark potential, and highest FPS, you gotta go with ATi right now - as they have the superior engineered product. Sadly, Nvidia has them beat at the software & support level. (Until Fermi is out, at which point they will have ATi beat on the hardware and software level.) A quick glance of the hwbot, oc world records, and overclockers forums will show you what gfx hardware they are all using currently, and it isn't GT200b's or GTX295's.
The GF100 GTX470 & GTX480 will be stellar, no doubt about it. Combined with the features and reliability of NVCP, a vast array of TWIMTB game support, and Phsy-X hackjobs, it is destined to deliver an amazing experience for the beginner and extreme overclocker alike. Nvidia should price it competitively, but I don't think they will, since they never have before. 448 and 512 SP GF100 parts will rule the high-end in a couple months.
