Hi, I have a WinXP Pro 1.8GHz 512Mb Pentium 4 laptop machine and do microarray analysis on it with R. However, it would do better with more RAM. So, if you're buying a new system then go for >1024Mb. Of course, this depends totally on what kind of analysis you do and how many arrays you work with (==have loaded) at the same time and so. Doing microarray analysis my thumb rule is that you get more bang for bucks if you put the money on RAM rather than the CPU; swapping takes time.
About QuantArray tab-delimited output files: Reading a 2.9Mb file using read.table() with optimized field types (colClasses - integers for integer fields and so on), object.size() says that the read data frame is 2.8Mb. So, without knowing your exact fields, maybe you can calculate with 16Mb per slide in your case.
