Virtually every GeForce 7900 GT card in the market now are, like the MSI NX7900GT-T2D256E, clones of the reference design. That's not a bad thing, since the GeForce 7900 GT possesses one of the better, if not the best price/performance ratio that we have seen from a high-end graphics card for a long while. The reference design opts for a small cooler bolstered by a copper heatsink with aluminum fins, making it a one-slot solution that should delight those intending to get two for a SLI setup.
Of course, this minimal cooling is the result of NVIDIA's new 90nm, die-shrunk G71 core and the use of 1.4ns DDR3 memory chips from Samsung running at 1320MHz DDR, which sits comfortably below its specified maximum memory frequency of 1400MHz DDR. The lower power consumption of the GeForce 7900 GT also makes heat a less immediate issue compared to its GeForce 7800 series predecessors, so there is no reason not to get the newer cards.
More so when you consider the extra vertex and pixel pipelines that the GeForce 7900 GT has over the GeForce 7800 GT. Not to mention the fact that the MSI NX7900GT-T2D256E when clocked at the default 450MHz for the core, is already 50MHz faster than the GeForce 7800 GT. MSI has also included its Dynamic Overclocking Technology (D.O.T) that aids in overclocking by providing a set of profiles ranging from 2% to 10% overclock. An added bonus is the fact that the end-user is covered for any damages by MSI for using D.O.T. Based on what we have seen, getting it to run at the maximum D.O.T of 10% should be a piece of cake and we have included some 3DMark05 figures later for your reference.
