You do realise that the GTX680 might be weaker than a GTX580 in GPGPU??

Look at the Toms Hardware charts,where the GTX580 seems to be faster in all but one compute based benchmark.

Hmm, interesting, I'll have to wait for some definitive benchmarks on the 680. I did use CUDA quite a lot, but mainly use a card for gaming so that's what will tip my decision either way depending on the performance gap at 2560x1440.

Oh I understand that, I mean you have to jump onto the carousel of computer hardware sometime. It's just that I only got it about a month ago, and now the 680 looks like it will be the fastest single-GPU card until 2013.

Just bad timing if that does turn out to be the case.

I have a buyer for the 7970 anyway if I do definitely decide to swap it out. He's offered £350 so it may just be worth it if I don't have to take a big hit.

I'll have to sleep on it a bit I think.

£350 ? go for it :) - doesn't matter the hit - its the price after buying the new card thats important - if the 680 is less than 400 and faster its still a good deal :)

There's nothing wrong in the 7970, you'd have to be mad to swap it for a 680

4fps more in bf3 hardly owning the 7970 like some sites claimed.I would sit tight for the next cards near christmas.They will surely have something big each by then.
 
AMD are going to regret their 7900 pricing, had they been more competitive when the 7970 released and even the 7950 they could have stolen SO many potential Kepler customers, including myself.
 
Yeah I wanna buy. I really do.
Until I see relative CUDA performance with the 580 I will hold off :(
The most frustrating thing is the 7970 is a GPGPU machine, solid. but the AMD SDK/drivers must be terrible since it's always being sidelined for CUDA. :(

must commend you on the great answers Gibbo, also was never under the illusion that the GTX 680 was a mid-range card, cannot fathom why some seem to have that impression.

so ~15/20% faster than the 7970, that is pretty reasonable if the price is right and AMD don't slash their prices on the 7970, there are also rumours of another 7*** graphics processor waiting in the shadows, any thoughts on that? rumours are processor to ruin NVIDIA ideal launch...? :confused:

AMD priced accordingly like most companies do, their 7*** series is still the fastest single processor card in the market, and has been since the second it was released. why do you think Intel charges a billion dollars for its extreme edition processors, because they are the fastest consumer, desktop processors on the market, simple as that, top of the tree therefore desired.
 
It might be the normal way of doing things but it didn't work did it? Loads of people looked at 7900 prices and decided to wait for Kepler, that's a fact.

Of course I would wait for more reviews to see how the card does in a range of games and settings,but performance looks decent at your resolution. Of course there should be some more benchmarks using CUDA too,so at least we will get a clearer picture in this regard.

In that case it should cost you little to get the GTX680. I suppose having at least some level of CUDA functionality will be better than none in your situation.

Win-win situation??:p

NVIDIA won't release a faster single GPU this year, the next faster product from both AMD and NVIDIA shall be dual GPU based.
Click to expand...

While I don't doubt that the NEXT faster card from both parties will be a dual GPU card, suggesting that there won't be another faster single-GPU (i.e. GK110) from Nvidia this year seems extraordinarily unlikely... I know you have access to different information to us, and it does your job no favours to advertise that this may be a short-lived product, but everything points to GK110 appearing later this year. For example:


1: Most accounts have it that the initial GK110 die has already taped out from TSMC. Unless there have been major issues, this would put it somewhere in the 4-6 months timescale for potential availability - depending on respins.

2: Far more importantly: GK104 is not a 'true' compute chip. A replacement for GF110 is required in the HPC market. A chip with ECC capability, full double-precision support, and fast interconnects.


Through the University HPC we are assured that the replacement for the M2090 will be appearing "this Fall", and will offer over twice the double-precision performance of current Tesla cards. GK104 cannot meet this spec, even with a Tesla-specific respin to enable 2:1 sp : dp performance (like the Fermi-based Tesla cards). So, with GK110 appearing for the HPC market this year, it seems highly unlikely that Nvidia would not release a gaming version alongside this chip. Historically, the gaming cards have always appeared before the professional versions (Tesla / Quadro), and there is no reason to assume this will change.


Anyway - colour me unconvinced. The only thing that will stop GK110 appearing this year is if it has further design problems, and needs yet another major redesign.
 
Depressingly true, guess this would be a stopgap purchase though I'm leaning on just buying 580 on the MM as people inevitably upgrade to the 680 for cheaps then...
Using CUDA on a few of the plugins on 3dsmax/premiere have been life savers in the past.

For single-precision (32-bit) compute, the 680 should still be something of a powerhouse - so long as you don't need the other Tesla-specific features, or have a mass of complex threads to schedule / balance.

The real issue comes with double-precision (64-bit) support, which is required by a significant subset of HPC applications.
 
personally looking forward to seeing what the GTX 660 (is that right) can offer? big fan of mid-range, multi-card set-ups and with Kepler being so potent, apparently perhaps they'll strike another GTX 460 style sweet spot in the market...? all good news in the end, competition = good for the consumer.
