Nvidia’s new card was a bit of a shock to us when rumors were flowing around the different communities, the card sporting only 24 Pixel Pipes and core clock of 650MHz was what seemed to be a disappointment to the communities. As ATI’s new X1900 was sporting a touted 16(48 pixel Shader processors) and up to 700MHz Core Clock. Some said if Nvidia was to take back the crown they need to have at least the same pixel Shader and a core clock of 750MHz+. Well I am here to say they were wrong about it having to exceed the clock rating of the X1900 series.

Not only did Nvidia create a card that would meet the X1900XTX head on, but they beat the X1900 in both single slot solution and in SLI in 60% of the benchmarks. Not only have they created a card that runs faster, but they made a card that blows ATI away in power consumption and efficiency. If you haven’t heard the 7900GTX 512 is really a shrunk down version of its big brother the 7800GTX 512 what I mean by this is the core. The 7900GTX 512 is Nvidia first flagship card to use 90nm technology, what does this mean to you? It means we get to benefit from a cooler running card that uses less power that still provides us with a huge punch in graphic performance.
Nvidia has once again given us a reason to smile. Now take in mind the 7800GTX 512 was just released 6 months ago and even than was in limited quantities and charged a premium we all knew we would pay anyways. right?. But I have to look at both sides of the coin; ATI also has the shortest lived release in the history of graphics with their X1800 series. So I guess both sets of fanboys for Nvidia and ATI has something to be grumpy about. It isn’t easy spending $500~$600 per card every 9 months, and if you have SLI or Crossfire you're looking at $1000+ to acquire what is know as the dream machine.
So let’s face the facts that the Graphics world is now on a 9 month wheel and we the consumer will always want the best of the best. So for now we will be spending our hard earned money that we tuck away from our wives or girlfriends to gain these 18% to 33% increases in gaming performance.

Oh man, that card was just plain ridiculous when it hit the market
I'd imagine that nvidia has speed binned the cores a little higher for the GTX cards. The stock cooler for the GT is also puny compared to the GTX, so I'm guessing that'll need to be upgraded to really push the core.
With the GT clocked at 450MHz Core you have a long leap to get to a GTX rating of 650MHz, along with the GTX can also OC pretty high as well. but if you look at this break down it should show you the 3 main differences... "look at the GT's bold ratings."
7900 GTX:
8 vertex pipes
24 pixel pipes
650 MHz core clock
1600 MHz memory data rate
512MB of memory on a 256bit bus
7900 GT:
8 vertex pipes
24 pixel pipes
450 MHz core clock
1320 MHz memory data rate
256MB of memory on a 256bit bus
Seems to me like the biggest difference is the amount of GDDR onboard. I think if I needed a gig of GDDR3 I'd just build a quad SLI system with 4 OC'd GT's and spend that saved $1k on a FX60 chip.
Here's a link to the XFX card on newegg.com: http://www.newegg.com/Product/Product.asp?Item=N82E16814150137
Thats a 110mhz OC stock out of box with the super cheap hs/fan and 330mhz on the memory (one reviewer got his up to 1800).
Best bet is to get GT and overclock to GTX speeds with artic cooler right?
jradmin - you could also use that 1k saved to get yourself a opty 170 OC'd to a fx-60 and use the extra $651-$50(cooler) to get yourself a 15krpm main HD and the cooler for your Video card + a trip to the strip club :necro:
What cooler do you guys reccomend for OC'ing the 7900 GT?
The XFX($349) comes at 550core and the EVGA($319) comes at 500core; why are they different?
Besides the fact that eVGA's support is A+!
They both should be able to OC to the same max speeds right?

Any of these should work good.
It *may* be possiable to get the card OC'd over 650 on air just because of the fact that these companies can do it on the stock cooler.
I think if your going to get it to 690 or more then your probably gonna need a liquid cooling solution. I definately see 650 - 675 as a real possiability for a GT on air.
The difference between the cards is only the provider. They choose to OC it as much as they want, and my experience with any stock OC'd card means that there is always a hell of a lot more OCing room outside the box. They are both the same cores and they should in theory be able to get the same max speeds, however its rare that 2 cores will clock the exact same thing due to nature.

It came out of the box at that speed though, it wasn't OC'd to that outside of the factory.
