Portable Work Environment

Have a look at Team Viewer. I use it on Video Editing HD videos but you probably mean higher end than that. I find the mouse to be as fast and as accurate when remote working as normal working. The program is free for personal use. You need a licence for commercial use but I think the definition of "commercial use" is when you give remote support to others for a fee!
Worth having a look at though, you can download it from here:
TeamViewer - Free Remote Access and Remote Desktop Sharing over the Internet

A good laptop you be your best bet, or a portable external drive if you are allowed to transport the files that way (you can now get external SSD's which would be extremely fast)....then you have local access from both machines on the same files.

VM would work but graphics would be an issue for you as you stated.

Remote access tools do not give you the sitting at the pc experience that you are saying that you need because of quick accurate mouse control (still lag issues existing in every remote desktop app that I have ever used, but I am far from an industry expert on remote desktop apps).

I have no lag at all when usingTeam Viewer as I said above;

I find the mouse to be as fast and as accurate when remote working as normal working.

Bobtran: a laptop is unfortunately not an option at this time.

Mitchell65: I've heard of Teamviewer before.... don't i need to give permission on the remote machine when accessing it from somewhere else? ...meaning, i thought the person on the remotemachine has to manually allow the connection, which in my case wouldn't work since I can be only at one place at a time.

My favourite solution would still be an external drive which i can boot from on different hardware profiles.... I thought by now something like that must be out there somewhere? ; )

Yes you need to give permission so it would not suit here, sorry misunderstood the problem!

Actually, TeamViewer has the option to setup a master password so you can login :)

That's quite true but you need to open the TeamViewer program to establish a connection and you can't do that remotely. I suppose you could leave TeamViewer open in the background but that would then mean setting the program to open on boot up of the remote machine.
