I am officially in the market for a new dev machine. :) My current machine is a 2.21 GHz AMD Athlon 64 (3400+) with 2.71 GB RAM, but it is slowing down and I cross my fingers every time it boots up. My hard drive is full and it just has too much crap on it. I always hibernate my machine because if I boot it up from scratch, it takes about 10 minutes before I can do anything with it. Yes, I admit, I miss my old DD MacBook Pro sometimes. :)
I'm considering reformatting this drive (my current dev machine), but instead of setting it back up as my main computer, I'd like to install Windows Server on it and run TeamCity and SubVersion and stick it in a corner. That way I can keep it running and develop from the laptop or the (new) desktop and check-in changes from either. Not only that, but Jen wants me to setup a place where we can store pictures on and access at anytime... easily. Currently, all of our pictures are on an external hard drive that is connected to my work machine. This means that I have a share on my work machine and she can only get to the pics when it's on. Even then, she has to go through hoops inside Picasa to get access to them (using a mapped drive).
The fact is that my machine is ~5 years old now (hard to believe), and I know there is a lot better hardware these days for a fairly small amount of money. I'm looking for a multi core machine with Vista (yes, I said it) that just screams and is built for a multi-tasking geek like myself. Any ideas?
