The first consumer marketed card to feature 2GB of RAM, let alone 2GB of GDDR5.

Wow, can't wait to see what Nvidia puts out next.

What a beauty...

It's so big, it'd be such a tight squeeze in my case. It'd get so hot in there and I...

Should probably stop typing now. Even though the previews we're seeing now are on prerelease drivers, the R700 card looks nothing short of impressive, a few benchmarks on AAT show almost 100% performance scaling per core (and often seems to soundly trounce the GTX280), awesome stuff from the red team.

HOLY SHIZA!! 230GB/Sec!! Jesus H Christ! Well, if this card is'nt a flop liek the 3870 x2, this might give me a reason to upgrade.

Well fellas, I'm actually an Nvidia Fanboy, and been using Nvidia since the 6xxx series. but sadly nvidia is throwing in the white towl for this year, since they also want to go DDR5 since DDR5 uses up less than DDR3's. the potientional of DDR5 is quite astonishing. looks like Nvidia wont impress us till early 2010. Checked it out at forums on slizone.com not sure where the link is, And might actually just be a rumor. But I believe Nvidia wont do much till late 09 earliest, Since they have to re design their entire line of VGA cards. the 09's are actually still based of the GTX200s with DDR3's. and Just upgrading to DDR5 on those might cause problems or something, so they want to redo and make sure its stable. but then again! might be false. some guy claming to work for one of the 3rd parties said so. I guess I'm going back to ATi till then. and also BTW ATI 4870x2 being 2gb is still un=official i believe, but the 4850 has been official since july 14th , Ill post link once i find these info.

MSI / GIG / Asus Is also coming out with 1gb 4850's

@ Eeek, nvidia is doing pretty good yet, i was impressed by the 280 gtx, but anyway the 2gb of ram is such a waste, and 1gb proubly is a waste two for gddr3, but 1gb for gddr5 will proubly be better

Ok, I'm sorry the 4870x2 is 2GB, and official price is going $549, mean while Just found out they might make another x2 which is 4850x2 and unlike the new coming 2gb 4850 DDR3, the 4850x2 will be 1gb of DDR5? price isnt official yet but looks some where around $399.00. Google 4870x2 Official price and the link comes out. I am hoping the
