The RV770, or ATI Radeon 4800 series, will launch on June 16, according to several sites. Graphics cards based on the first GPU in the series, the Radeon 4850 with 512MB GDDR3 memory, will be available immediately for $230. This GPU is the follow-up to the current Radeon 3850. Higher-end cards based on the Radeon 4870 with 512MB GDDR5 and the dual-GPU Radeon 4870 X2 with 1,024MB GDDR5–a first–will be announced on June 23. The Radeon 4870 cards won’t ship immediately because of the lack of availability of GDDR5 memory, but when they do show up prices should be around $350. The Radeon 4870 X2 cards won’t show up until early 4Q and will cost about $550.

I knew the rumors of those cards being similarly priced to the 3800 series was too good to be true. Oh well, I was planning on waiting until the end of July to upgrade anyway.... maybe the prices will have dropped a little by then.

well, ATI seem to have been pretty good to us giving all these dates, looks like i'll have to try my best and nab a 4870xt when i can

Theres no such thing as the 4870XT theres the R770XT chip but the name of the card is the 4870. AMD/ATI ditched that naming convention to make it easier on users.

Don't you find it interesting that these newer GPU's are still using 512MB VRAM? Which is exactly what ppl say is the 9800GX2's limitation in higher resolutions with AA enabled. Maybe 512MB isn't the issue afterall...

I personally believe the G92 core itself is the issue. Since the 9800GTX has less bandwidth then the 8800GTX and more performance. That rules out in my mind that it is bottlenecked in memory.

Possibly down to bad driver implementation at present. I mean memory management for these cards is all over the place. Also Nvidia are still to release their CUDA software, which could turn everything on it's head. Will GT200 be faster than a 9800GX2? That's the question.....in all likelyhood probably not, but it might be more efficient at things and not so complicated to write for.

I thought that most people agreed that the problem with the 9800GX2's at higher resolutions is that they are severely bottlenecked by the 256bit bus which the HD4870 wont have.

Shows how much you know about the 4870 then doesn't it. It clearly shows 256Bit itself.
