With ATI's latest Radeon graphics card already getting benchmarked, I guess cardmakers decided it was silly to wait until June 25 for the official unveil-pretty much everybody is popping the Radeon HD 4850 right now-they're all over Newegg and assorted other merchants. Built on a 55nm process with 512MB of DDR3 memory running at 1986MHz and a clock speed of 625MHz, it's got 480 stream processors (480 was old number, it's actually 800) and support CrossFireX up to four graphics cards. While the MSRP is $199, you can pick one up for about $174.99 after rebate. [Newegg]
