Pros: I have bought the card, it does have DDR5. The DDR5 memory clock is 750Mhz (3.0 Ghz effective), giving it 96 GB/s throughput vs. 64 GB/s on a stock 4850 with DDR3. Verified using GPU-Z. Specwise, it looks like a 4870 with a 17% drop in memory clock, a 4850 GPU clock(625 Mhz v. 750 Mhz for the 4870), and a 4850 BIOS. OC'ers can make of that what they will. Temps are about 45-50C idle, 60-65C at load.
Cons: Doesn't support DX11. Eight pin power connector suggests it might be a bit of a power drain.
Overall Review: I planned to do a little more testing on this before posting a review, but felt it was more important to quickly correct some of the speculation regarding the memory specs with real data. I'm glad I bought it. The performance matches or beats a Radeon 5750 - if you can live without DX 11, this is a bargain. Kudos to NewEgg's shipping dept. Ordered this on Thursday at 1:00 pm; received it on Friday at 3:00pm.
