Hello folks After selling some guitar gear and saving up, it looks like I can afford a new 17" MBP. At the moment, I have a 2.3 C2D, 3GB RAM, x1600. So it's quite a big upgrade! I have a few questions I'm sure most of you can answer. 1. Is there a big difference in DDR2 and DDR3 RAM? I'm 'only' getting 1GB more, but since its running at almost twice the MHz, I expect quite an improvement. 2. I'm going with 4GB initially,because apple charges too much at the moment for the upgrade. I know not a lot is known about this, but I assume simply taking the whole bottom piece off will give me access to the RAM? 3. I want to play a few games on Boot Camp. With the new 17", it looks like it will be able to handle most of them. However, is there any advantage of me buying Vista? Or should I just stick with the XP I have (can XP read DDR3 RAM, etc..) 4. The loss of a firewire 400 sucks! Will I lose performance if I get a 400->800 adaptor? I have an audio interface and harddrive dasy chained to my 400, and I need them. That's all for now. These are my planned specs: 2.9GHz upgrade, 4GB RAM 320 7200 upgrade Anti-glare (matte) Applecare. I can't wait Thanks folks!
