can a T60p support Revit 2012?

[antelope]

Summary:
I am an architect and I need to get Autodesk's Revit 2012 installed on a home machine so I can learn the program. I have a T60p with 4Mb RAM (3 useable per system). Will this system be able to support Revit? I don't expect to create very large or complex models on this computer (think houses) but I'm not sure if it will work at all.

Details:

T60p specs are in footer below. Per Wikipedia, the ATI Mobility FireGL V5200 256 Mb graphics card supports DirectX 9.0c and OpenGL 2.0.

Revit 2012 wants (copied from their site, partial list):
For Microsoft Windows XP: Intel Pentium 4 or AMD Athlon dual core, 1.6 GHz (or higher) with SSE2 technology
4 GB RAM
5 GB free disk space
Display adapter capable of 24-bit color for basic graphics, 256 MB DirectX® 10-capable graphics card with Shader Model 3 for advanced graphics (note this caveat)

I think my the main possible issues are: processor, RAM (4 wanted vs 3 useable), DirectX 10 wanted vs 9 installed, and maybe the Shader Model 3. I don't know if the latter two are only if "advanced graphics" use starts pushing the graphics card.

A couple other things to note:
- I seem to remember when I looked into this a couple years ago with Revit 2009 (+/-) that the FireGL5200 card was considered sort of borderline on a list of graphics cards that Autodesk maintained (I can't find an updated version of that list). For Revit 2011 3Mb RAM and DirectX9.0 were considered OK for system requirements.
- The ATI Mobility FireGL V5700 card is considered an Autodesk "certified" product for running Revit 2012. Differences are 516 Mb memory and support of DirectX 10.0 and OpenGL2.1.
- I'm eligible for the student version of Revit (free) since I'll be taking a class at our community college. If I was spending $6000 retail for it then just getting a new system would be part of the program. However, I'm trying to minimize expenses since I don't have any work (common issue for architects).

Any help or suggestion are appreciated. I could just install the software and find out if it works but I'd really like to have a sense if I'm probably looking at a new machine (which then means messing around with trying to get a new activation code if the program is already installed).

Just in case anyone else is interested in this I thought I would give an update.

I also posted this question at Autodesk User Group International (AUGI) in the hardware forum. I got a couple of replies which both said it would maybe, barely work. Here is the link:

Definitely at the bare minimum to run Revit...

You can download the demo and see for yourself it will run or not...If you do any renderings more than likely you won't be able to save them as there isn't enough ram, and XP doesn't manage it very well anyway.

Probably good enough to learn....but I'd make sure you have nothing else running at the same time as that memory is very valuable to make Revit work right. HTH

It's kind of like asking "Can I run a marathon in sandals?"

You can, but it will make you hate marathons.

If you really care about Revit get a 2000$+ Dell Precision or Lenovo W workstation

(nice analogy)
