And even if you have HDX or a TDM cards you only get to run plugins on the, that support that, otherwise they run native on the host CpU. You can also run Pro Tools HD with other interfaces for the extra software features.

If you have to ask questions like this you probably don't need HD. Folks that do need it tend to already understand the benefits and limitations, and importantly costs involved. Be especially careful of thinking this will just be "better". Tell us what problem you are trying to solve and what you do and folks here will be able to give you useful advice. Is tracking through plugins or latency the issue? General CPU load of plugins? System not stable? Running out of CPU running VIs? (DSP won't help you directly there). Etc.

Give detailed specs for your current system.

"core" generally refers to an old TDM card, if you are really interested in HD TDM legacy systems you are posting in the wrong forum section. HDX cards are generally just called that.

He has the basic specs of his system listed. Its not compatible with HDN/HDX, nor does the Pro Control work past PT 10.

He would have to search out some pretty old HD cards for slot compatibility (PCI-X?) and a license. Be much better off updating the entire system, though that would be quite expensive in comparison.
