Quote from Scataphagos:
As far as how much RAM you actually need, check your Task Manager when all trading apps are loaded.
Can you find someone in the US to buy from Dell Outlet and send to you?
Win 7 pro 64 bit requires 2GB, TWS says 4GB+ and I'm most certainly very much on the plus side as I could see the performance degradation once I had it configured to my liking.
Re Dell Outlet, they are very specific about only shipping to end users addresses, so going that route would void my warranty. It would also put me at the tender mercies of the Thai customs department, something you don't want as I found from personal experience. If a company ships to me and accepts the task of getting stuff cleared, it is not my problem.
Like the Dell quote I was given, I know for a fact that the goods will be shipped from the Malaysian plant in Penang, but the quote I get is 'delivered', ie Dell has to get the customs clearance and pay duties at the appropriate rate.
