Nvidia has the edge with GPGPU functions. The GTX 285 and 295 may be too expensive for serious consideration, but the revised core and slashed price of the GTX 275 makes it a far more tempting proposition.

The GeForce GTX 275 was launched with one sole reason only, to battle off the Radeon HD 4890. It's the cat and mouse game that ATI and NVIDIA have to play against each other. Competition is what makes this technology evolve and affordable, don't you ever forget that. By doing so NVIDIA accomplished it's mission absolutely.

It is clear from the performance figures achieved by the GTX 275 that it is a very desirable product. Throughout our testing the card was often leading the pack and regularly produced higher minimum framerates than the competition. CUDA/GPU computing continues to impress us and new additions such as vReveal detail just how useful and flexible the GeForce GPU can be. They should have a very popular product on their hands and one that it is hard not to recommend.

...which would we choose if given £200-£225 right now? We'd give the nod, just, to the GeForce GTX 275, because it matches the Radeon HD 4890s on price and performance, is a little quieter, draws a touch less power when idling, and is backed up by more-robust GPGPU environment.

If you tend to leave your computer on for long periods of time when not gaming, you may appreciate the lower idle power of the GTX 275. Likewise, the wider software support for CUDA, over ATI Stream, may attract you to side with NVIDIA, especially if you work with video a lot - be it editing or trans/encoding

For ATI to deliver more performance to trump Nvidia's GTX 275. ATI will have to push the clock speeds even higher, producing an even hotter, more expensive and probably louder card. Either that, or it'll have to look into a re-vamped HD 4850 X2 card based on a pair of RV790 GPUs (likely downclocked and with the GDDR3 memory controller enabled).
As it stands, the GTX 275 with the ForceWare 185.65 beta driver is the clear choice.
