...If you plan to purchase this card performance wise and use it for typical fashion / regular gaming usage, there's just hardly any gain to find. It's a bit unfortunate, because I really do like the idea of a manufacturer being creative this way. But facts are facts and anno 2008 a 2GB framebuffer is pretty much of no use. So for that you might as well go with the 512MB or even the 1 GB version.

Overclocking wise again we go into two directions. The core frequency of the GPU we could push upwards pretty easily. Combined with the cooling solution at hand, and the handsome 3rd party overclocking software like Rivatuner, the sky is the limit. However it is the memory that is a limiting factor. We could barely overclock it at all. And if anything, the 4850 can very much need extra framebuffer bandwidth.

Conclusion
...The Zalman GPU cooler used on the Toxic HD4850 cooled the card quite well. Idle temperatures of 35 to 38 degrees Celsius, and load temperatures of 60 to 64 Celsius - with "zero" noise - are a huge improvement over the standard cooling used on the 4850 series cards - no BIOS or software modifications needed. Those solutions worked for the reference cooling, but they came with a penalty - extra work and noise. The fact that the Toxic is an overclocked card means that the performance should exceed that of a non-overclocked version, which it did in 27 out of 32 benchmark tests. In four tests, the performance was equal (usually the lowest resolution tested), and it actually lost to the stock 4850 in one test...

Pros:

• Performance
• Cooling performance
• Additional headroom for overclocking
• Bundled software
• HD capabilities
• Price
• Aftermarket cooling

Cons:

• Did not win all the benchmark tests
