The latest rumors are May 14. As for accurate info on the release date, we'll have that when they actually appear or ATI makes an official announcement. Anything before that is rumor and speculation. Sorry but that's the best I can tell you.
Yeah, rumors are all over the place, anywhere from today to the end of May. The credible release date is mid May (as stated by Senor_Bob). But, the only thing we know for sure is that it isn't today.
Something interesting I noticed was that THG said "Nvidia isn’t sitting still as AMD is preparing to reclaim the performance crown for graphics cards later this month." in their article about the 8800Ultra.
Just a joke.
I am sure the guy writing the article was just careless or stating AMD's intentions, not the truth. But I thought I just had to point it out, I am getting pretty desperate for any news on the R600, so even this caught my eye.
ATI trashed the r600's .......... and the ddr4 video card was slow and junk ....... so guess for yourself .... they ain't got nuttin to sell !
You know this how? DailyTech already admitted they didn't actually have an XTX with DDR4. Now the thing may suck the way you want it to but it might be awesome - WE DON'T KNOW YET - STILL WAITING FOR REAL BENCHMARKS!!!
