Went for GTX 670 Windforce 3X. Will be my first time using Nvidia after using AMD for many years. It better be worth it.

I got back into M FSX again and Nvidia are meant to be so much better for FSX, so we will see. :rolleyes:

Should work well, the newer 79xx cards have problems with drawing clouds and shaders from reading around a few sim forums but the GTX680 has had some good feedback from FSX users so would expect the 670 to be good too. Be sure to post your experience here or on the fsx thread! :)

Well at this rate AMD will soon have to lower 7970 prices to 6***series prices to flog em:eek::D:D:D:D:D:D

These sort of posts are idiotic as we don't have any info on sales at the moment. When you think a gtx 670 at 1187mhz matches a 7970 at 925 MHz, its a no brainer who wins when the gtx 670 is overclocks around 10-15% and the 7970 over clocks by about 30%.

Yup, exactly what I think. Will be interesting to see how long NVIDIA hold back the GK110?

They can wait as long as they like, no game will utilize more than the 680 can give in the near future.

And with the 7970 worse than the 680, there is no point in bringing out the GK110.

If they did they would just ruin their sales of the 680 which, from a business point of view is a terrible idea

The average 7970 does not overclock by 30%.
 
Its been known since the 680 launched that it was a renamed 670 Ti.

GTX 670 Ti - full GK104, 8 SMX modules, 256 bit memory interface, 2-4 Gb Vram renamed to GTX 680 and heavily overclocked.

GTX 670 - GK104 with 7 SMX modules, everything else identical to the above. For £100 difference its a no brainer to buy this instead of a GTX 680.

GTX 660 - GK104 with 6 SMX modules, 192 bit memory interface, 1.5-3 Gb Vram.

There kind of is still a potential GTX 670 ti from this line up - fully unlocked GK104s that cant run at GTX 680 frequencies, it makes zero sense performance wise, but it makes sense for Nvidia to sell fully functional but lower binned GPUs for as much as they can rather than purposefully crippling an SMX module to sell them as GTX 670s.
 
Hard decision for me now between the Windforce 3x 670 or a 7970. Would like to see them both benchmarked at their max overclocks as the 670 is hitting 1150Mhz+ in the reviews to give it that performance so an OC'd 7970 may still be a better bet.

From a little research I did,it seems many of the GTX670 cards being reviewed hit 1084MHZ:

Nvidia quotes 980MHZ for the GTX670 so it seems this is inaccurate.

This is from one of the reviewers on Hexus:

I can give you a bit more insight into the GPU Boost frequencies of a partner card. We have a KFA2 GTX 670 EX OC card in atm. It is clocked in at a default 1,006MHz core and 1,085MHz GPU Boost, based on NVIDIA's average frequency-adjusting speed.

However, tested inside a Corsair 600T chassis with the ambient temperature at 24°C, we can log the frequencies in each of our real-world games and then present them to you. The following core/shader clock is the one that is running the majority of the time in the following games, though it does drop just a touch when dealing with particularly intensive gaming sections.

AvP

1,188.9MHz

Batman

1,175.8MHz

Battlefield 3

1,188.9MHz

Crysis 2

1,188.9MHz

Just Cause 2

1,175.8MHz

Shogun

1,175.8MHz

What you can see from these results is that the GPU Boost is far more aggressive than NVIDIA alludes to, to the tune of being around 100MHz higher. This is the reason why the GTX 670 benchmarks so well; it bombs past its nominal GPU Boost, which equates to an 80MHz uptick over default. Memory speeds remain at the default 6,008MHz. Compare this with a stock GTX 680 and the in-game speeds are higher for this second-rung partner GPU.

Now considering that the card we have is being sold by retailers across the country it is unlikely to have been cherry picked. We can't know this for sure until we receive an identical card from the stock of a retailer, absolutely, but the feeling is that NVIDIA's declared GPU Boost frequency for the GTX 670 is way too conservative. Indeed, as you will see tomorrow, this partner-overclocked GTX 670 is as fast as a stock GTX 680.

Bottom line is that the highly aggressive nature of GPU Boosting on GTX 670s makes them an even better buy, though, on the flipside, you may not have too much scope to manually overclock the card much further.

It looks like AMD's accountants will be biting the ends of the pens off while there working out how much their going to have to discount off the 7950 and 7970 to make them more competitive. If/when AMD moves the price of the 7950 there's a chance they will also have to start discounting the 7850 and 7870 if the 7950 goes down to £230 a shove.
