if you were waiting for R600, it is a good thing you did. There are some really nice advances incorporated into the HD 2900XT and the Vista performance of the 1GB GDDR4 cards have made it the choice of boutique system builders (I just wish we had them in house). At $400 for the version we have in the lab, it is a good price as it has more to offer than the GeForce 8800GTS. The sweet spot is still the 320 MB version of the 8800 GTS but that could change as other versions of the R600 family emerge. Until then, if you were sitting on the fence, you can either keep riding or finally spend you money on something. Versions like the Sapphire HD2900XT Toxic will come factory overclocked with a stand-alone water cooling solution.
Overall, HD2900XT is more forward looking than GeForce 8800 and it should be; it took an extra six months getting it to market. If you are leaning towards longevity of a card, R600 looks more attractive with a dedicated tessellator, programmable filters, high-clock speeds and crazy amounts of bandwidth. It is a hot and a little loud.
Final Thoughts
We are going to look a little more into the power consumption of the cards as we found some interesting behaviors within GeForce 8800GTX and R600. To wet your appetite, here are a few of the findings. For starters, R600 drew less overall system power than GeForce 8800GTX in the game tests.
