Thanks for the quick answers.
The dual 2.0 is the same one offered on the Apple Store. Dual 2GHz, 1GHz frontside, 512MB expandable to 4GB (upgraded to 2GB from Apple), 16x double layer Superdrive, ATI Radon 9600 256meg upgraded, Apple Care.
$2358 with an free ipod mini (educational discount)
The dual 2.5 is same one offered a generation before. Dual 2.5GHz, 1.25GHz frontside, 512MB Upgraded to 1.5GB (1GB special at MacMall for $40), 8x Superdrive, ATI Radon 9600XT 128 megs, Apple Care.
trying for $2529 (trying to get system for $2199, this what it was being sold for at our Compusa, but I was to late)
There still are some 2.5s out there from different companies that I might be able to try to get a better price. Just wondering if it is worth it or should I just get the 2.0 from Apple.
