Thanks Algofy, I chickened out. I saw the site, spec'd a similar machine which would be hundreds cheaper. But I finally ordered from
http://www.tradingcomputers.com/index.html . I felt I might miss something trying to spec a PC without really knowing what I should. The one I ordered will have some software on it to optimize CPU usage for trading. I got a 3 yr wty, a back up HD. I also, reluctantly, got W10 so I won't be left hanging when they don't support W7 anymore. The sales guy said they haven't had problems with W10 for the last 8-9 months. Hopefully this set up will last 3 years til I find out whether or not I can make it as a day-trader.
