Expected for June, the NVidia GeForce GTX 285 is now available in pre-order from the Provantage website in USA.
Its price tag is most likely designed to directly compete with the Radeon HD 4870: 436.66 USD. Interestingly, the Mac Edition is "only" 60 USD more expensive than the PC version (from the same website). This will be a cheaper alternative to the Mac Edition Radeon HD 4870. However, as we reported it earlier, the PC version of the Radeon HD 4890 might be a perfect alternative too.
