That's amazing the whole build (compile+link) in 6 minutes!

Yeah ramdisks are generally faster and yeah i'd need to spend a bit on
ram as well.

Very helpful! Thanks. But I am pretty sure I wouldn't need SLI bridge
as it'd just run off elcheapo graphics (I wouldn't do game on it).
Rest of the features are very good.
