http://www.**--****.com/ Microsoft has signed a deal to license Nvidia's graphics technology in order to have the Xbox 360 backwards compatible--finally putting to rest the question that lingered behind current-gen Xbox users. The next-gen 360 uses an ATI chipset, whereas the current Xbox uses an Nvidia chipset. Since the two companies are rivals in the GPU market, many analysts were skeptical that Microsoft would deliver. The company made a cryptic announcement at E3, saying the "best-selling" Xbox titles would work on the Xbox 360. Microsoft since then has become more optimistic about backwards compatibility, with Microsoft Xbox PR Manager Michael Wolf saying, "our goal is to make all Xbox games play on Xbox 360, and at launch we'll have a selection of the top selling that will be tested and confirmed to work."
