My lab has an ~80 chip affy Exon study planned for the near future which I'm planning to analyse using R/Bioconductor. This will be a first for the lab so we have no dedicated computing hardware other than the usual desktop PCs etc. but do have some budget to get in a dedicated machine.
So I'm trying to get advice as to what spec of hardware we'll need to analyse this effectively without driving a coach and horses through the budget. Thoughts so far range from a 6 core (i7 975), 64 bit OS, with at least 8GB Ram if not a lot more with a sizeable price tag to match down to a quad core machine with 8GB at a tenth of the price.
Does anybody have any insights into what level of processing power we'll really need to do this analysis well?
Many thanks for your help.
