Is it just me or does the 7800 core features look A LOT like a streamlined 6800 core with improved pipes, and new features/updates??? Think about it... take a look at the review in CGW and look at the specs on the web. Its not the giant leap that the 6800 was over the 5 series... its VERY VERY simmilar to the arcitecture of the 6800

No. G70 is a new architecture, but it's taken a lot of cues from NV30's (FX5800) descendants. At least, such is my understanding. And the SSAA and MSAA modes for transparent textures alone is a huge leap forward in the IQ department. So much so, in fact, that nVIDIA has now rightfully reclaimed that title from ATI, who has held it since the 9700 Pro was released.

Only nice features the 7800 Series has is the transparent textures. Besides that it's cheaper to pick up a a single 6800gt because it can run all games out on maxed out highest settings smooth like a babies butt or go dual 6800gt and out beat a single 7800gtx in speed by 30%.

SLI with 6800GTs will also increase the cost by about 30%...

Still makes no sense. Same performance for $200 less. Can't forget added power requirments, and more expensive board you would need to run sli.

If you already have a SLI bored and a PS that can take dual video cards then its better of getting another 6800. Thats what i'm doing. Why pay $600 for a new card when I can get one for $200 and out beat a single 7800gtx im speed. Why waist my SLI bored.

Because to start, you can now score an eVGA 7800GTX for $510 shipped from Monarch. Second, there's rather credible talk out that there G70 actually has 32 pixel pipelines--not just 24--but that current yields are too low to ship them as a product yet. nVIDIA may be stockpiling those high-yield cores to make an "Ultra" part sometime in the future. There's already a picture of a dual-slot cooling setup incorporating a fan that blows out from the center of the card over two heatpipe-equipped heatsinks. If such a part is ever realised, then the price of a GTX will pretty much be forced to drop a few more percent over whatever it winds up stabilising at. Third, before you start with the "but you need identical cards!", nVIDIA was talking about future revisions to nF4-SLI being able to support same-core cards from different manufacturers, period. This should be something that could be implemented with a simple driver update or BIOS flash. Fourth, prices of 7800GTX parts are still dropping: they're down about $60 on average from last week, ranging from about $510 to around $570 for the ripoffs. Fifth, for us IQ freaks out there, the ability to antialias transparent textures alone is worthwhile. Now please show me where you can get a $200 PCIe 6800GT (and don't tell me that you'd seriously go SLI with a standard 6800). Now then, if BF2 is anything to go by, then even 6800Ultra SLI rigs are going to choke on the upcoming generation of games, relative to a single 7800GTX. You'll also, for the record, notice that a 6800Ultra SLI setup doesn't scale as well to high resolutions/AA settings as the 7800GTX does. That is, the performance hit taken by the 6800U's is bigger--relatively speaking--than that taken by the 7800GTX. Finally, don't forget that there are still titles that either don't support SLI or don't benefit from having it enabled. In fact, I'm looking at a review (of a reference board) that pretty well suggests that even a 6800Ultra SLI rig can only keep up with a 7800GTX in most cases.

eekx.gif 32 pixel pipelines? Holy crap! Thats double the amount of my XT!

Thats what the r520 should have, the RSX from nivda may have that many. They said 7800gtx's in SLI was a taste of the PS3's power. I am happy with my 6800gt for now, spent $300 on it. C and a bunch of number could you show me an example of Af on transparent textures?
