I don't hardware box, so cannot help.
The wiki has some information on both hardware and software boxing.
You'll need to ensure your individual systems are capable of running the game smoothly enough on the settings you desire.
If your new hardware accomplishes everything the old stuff mentioned in stickies/wiki does, it will be fine.
If there are things it does not do, then I'd just go with the hardware mentioned in the stickies, because that will work.
Search is your friend, but someone with hardware knowledge might respond.
