Hey, thinking about getting a new powermac.. My question is: Is the NVIDIA GeForce 6800 Ultra DDL work the extra 600CDN? I want my computer to last, but also $600 can go a long way. Will the 9650 be able to drive the 23inch studio display with ease? I don't buy a computer to play games, but I do have a couple, does the 9650 have the power to play games (ut2k4 mostly) on a 23inch display with high resolutions with little to no lag? Also, is it overkill to get the NVIDIA GeForce 6800 Ultra DDL and run it on a 20inch display? Because I may only have the money to buy a G5 and 20inch with the NVIDIA GeForce 6800 Ultra DDL, but it's more conceivable for me to afford a PM with a 23 inch and a 9650. Also, should I go with the 2.3 or the 2.7 and is bluetooth addable after purchase like airport is? That is another case of $600 difference. One last thing, when my buddy ordered his 2.5 he was able to get the NVIDIA GeForce 6800, and it wasn't the Ultra DDL, can you still do that? Apple's site doesn't list it now, but I don't remember it ever listing it. Suggestions?
