Re: building/buying a pc for music writing
Welcome to T.F.!!
Get the E6550 for the CPU. It's just as powerful, but cheaper.
It's only that you get the 64-bit editions of Windows, that you can use more than 2GB of RAM effectively.
You don't need more than 2GB of RAM. Music editing software, is not a memory hog. 2GB will be more than enough.
For graphics, an onboard will do, or just some cheap card, like an 8500GT.
What's your budget? It would be better to build it, than buy it pre-built.
