Whoa. Just read that article. Seems that WinXP 64 makes better sense by far to drive my new Intel i7 PC. The speed difference is quite significant. I might have just wasted money shelling out on a Vista 64-bit installation disk.
Is Amibroker 32-bit pretty stable on WinXP 64? I only have experience running it on WinXP 32. If I only plan on running AmiBroker 5.24, TWS 892, and other basic 32-bit trading tools on the PC (and maybe Firefox and Outlook), would WinXP 64 be the way to go, or are there hidden disadvantages in going with that OS? I am aiming for the fastest backtesting platform possible. --- In [email protected], Keith McCombs <kmcco...@...> wrote: > > Dingo -- > Please read > http://www.infoworld.com/article/09/01/22/03TC-windows-multicore_3.html > for some comparisons between Vista64 and XP64. > -- Keith > > dingo wrote: > > 50% longer for AB to run - hardly believable. > > > > d > > > > On Thu, Mar 12, 2009 at 3:51 PM, Keith McCombs <kmcco...@... > > <mailto:kmcco...@...>> wrote: > > > > A few personal thoughts: > > 1.
