Nvidia landed an astounding blow to AMD last July pulling the GeForce GTX 460 out of nowhere and quickly taking the lead as the best mid-range graphics card on the market. It's only been a few weeks since and the 768MB version of this card can now be had for as little as $170, crushing the Radeon HD 5830, and questioning if the slightly cheaper Radeon HD 5770 is worth the money.Those looking to spend a little more also have the GTX 460 1GB at $220, which we have found to be comparable to the more expensive Radeon HD 5850 on most scenarios. As we've been mentioning in our recent GPU reviews, it's not just the value and sheer performance of the GTX 460 that has helped to make it a hit, but the combination of that with wide availability, low power draw, and cool operating temperatures.
