Hello guys... Here is my dilema
I actually have a MacBook Pro 17" 2.4GHz with 2GB SDRAM and I want to have something more comfortable to work at home.
I have $1,800 to invest in these two options... Get a 24" iMac or make some upgrades to my MBP (4GB of RAM, new hard disk with 7,200rpm with 320GB space) and the new 24" cinema display.
Now I have a question about the second option... My MBP come with a GeForce 8600M GT with 256MB of RAM. Would this video card be ok with the 24" cinema display?
Another thing is... would it make that much of a difference 7,200rpm hard disk from the 5,400rpm that my MBP came with?
Thank you guys for your comments to help me decide...
