I've actually done exactly this exercise myself having been constantly frustrated with the development platform in use at my company (Similar Dell PCs, Win 7, VS2010, RS6 etc.). Additionally we have a slow VPN to our servers which are hosted at our main office. There have been days where the total wasted time is >25% of my day.
I'd add an additional cost into the analysis which is the frustration of engineers working under these conditions and the risk of them leaving to find somewhere that takes this more seriously.
I'll also register my continued surprise and disappointment at the performance of this typical MS development stack on a machine that should be more than up to the task (3 GHZ Core 2 Duo, 4 GB RAM).
