Graphics cards and Performance

What level of graphics card is being targetted for Java2D acceleration improvements? E.g. if I buy a new Dell Optiplex, for many models the default graphics card is an ATI Radeon 1300 Pro 256MB. Will this miss out on some of the improvements in JRE6 or expected in JRE7?
My interest is two fold: (a) what my clients experience is likely to be, and (b) what I should get for my next development machine.

Hi Mark,
The shader-based acceleration enhancements that we've been adding to
Java 2D's OpenGL pipeline work on all shader-level GPUs, including the
first-generation shader boards that came out about 5 years ago. Another
way to put it:
ATI: Radeon 9500 and above
Nvidia: GeForce FX 5xxx and above
Those boards are really old by today's standards, but still are capable
of making the aforementioned operations go much faster than in software.
Shader performance improves greatly with each successive generation of
GPU hardware. My blog will have more detailed performance data, but
it's safe to say that an ATI Radeon x1300 should do well for these
operations (although Nvidia drivers tend to be more reliable, but ATI is
starting to catch up).
Thanks,
Chris

Thanks Chris. Is the situation similar for the DirectX pipeline on Windows (in terms of hardware required if not performance achieved)?
My about to be retired machine has what was the standard Dell offering when it was purchased 4 years ago, an ATI Rage 128, which provides precisely no acceleration at all (as far as I can see). What is worse is that it has proved impossible to upgrade (it uses the old 1.5V AGP) to anything more recent.

The current DirectX/Direct3D pipelines have fewer restrictions on the
hardware
(since they don't use advanced features like shaders), so you should
be fine.
The upcoming new Direct3D pipeline would require a DirectX 9- compatible
board. Most of the boards sold in the last few years should be fine.
Performance will vary, as some of the on-board chips (Intel, VIA)
are no speed demons when it comes to 3D acceleration..

Do a favor for me: take out that Rage 128, take it outside and shoot.

I'd like to, but only criminals have guns here!

There's a new Direct3D pipeline in the works???
Dmitri what's it going to take to get you start a blog? You cant let Chris and OGL steal all the publicity forever!

Yeah, Dmitri, what's taking you so long to get a blog? Your adoring
public (and I) are not-so-patiently waiting
