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.
