Hello guys in a week I will buy a new GPU, so I want to ask if a 660 ti ( overclocked by me) is better than a 7950.My budget is 310-320 euros so if you have any recomendations feel free to give a link !

I would pick the GTX660ti.
You want to read this article which looks at the difference in consistent frame times between a GTX660ti and a 7950.

As to overclocking, I would just buy a factory overclocked card.
Graphics card makers are wise to overclocking and bin their chips so the best ones can be factory overclocked and sold for a small price premium.
You will get fair value for the difference in price.

And... As a different selection criteria, I will always prefer a card with a direct exhaust double slot cooler.
That gets heat directly out of the case. Otherwise gpu heat stays in the case heating up the cpu and the graphics card. Not good.
Look at EVGA which has mostly that type.

Thanks for your reply, I thought open GPUs where better than closed ones

They are, ... in an open testbed where heat is easily dissipated.
But most of us install a graphics card inside a case.

Do not make too much of this point though.
The newer 28nm cards(GTX6xx and AMD 7xxx) run cooler and quieter so the graphics card cooler is really not so much of an issue as it once was.
Vendors put fancy coolers on the cards to a good extent for marketing.

Also don't waste any extra money on a 3gb version of the 660 ti. Lots of tests (Google it) show the the memory bandwidth of the card is the choke not the memory amount. Most cards with 3gb of memory tend to be 1-2 fps slower than the 2gb one.

There I saved you 20 bucks.

Wow you have been given some very bad advice here, definitely the 7950 is the card you should get. The GTX 670 is competitor to the 7950 and not the 660ti! Also a 7950 with mild overclocked will b faster than any card out there, sure the Kepler card overclock as well but do not scale the the 7000 series.

I might have thought so, if you go by Tom's heirarchy chart.
But after reading this report on consistency of frame times between a GTX660ti and a 7950, I wonder.

I think you are the one who is incorrect.

Reference:Tom's charts 3dmark11
7950 - 6440
7950 OC - 7100

660 (NON TI)- 6480
660 TI - 8530

670 - 8150-9085 some lower performers here.

Benchmarks and Crysis frame rates generally agree that the 660 TI is roughly equivalent to a 7950, and there are plenty of variables involved, but to outright say a 7950 is faster than a 660TI is just incorrect.

Overclocking will further the gap

GTX 660ti won't stand a change against HD 7950 if overclocked.

Exactly AMD's mistake was underclocking the 7950 to begin with


An amazing review right here

an Overclocked 7590 @ 1200Mhz beats out an overclocked GTX 680!

Redeemer, there is a new, more accurate way of measuring the speed of graphics cards, far better than the average FPS you are using.

http://techreport.com/review/23981/radeon-hd-7950-vs-ge...

Please, read the entire article. It indicates that the Nvidia cards tend to not choke on a few frames, but rather are smoother. They determined that by looking at the worst one percent of the frame times, the card that is slower there is the least desirable one, even if the other card has a higher average FPS. It is how slow your slow frames are that is most important.

With this new standard, Nvidia is king. Read the entire article first before making snap decisions.

the problem with the TR is that it wasnt able to be duplicated in all user systems. People are sel;f testing their frame latency and only some are getting the problems. If you look at the older charts, the latency only came with the 12.11 on some of the cards and hasn't affected them all. I also recall that like a german site or swedish site tech reports follow up video had put up videos of the frame latency in slow motion, where it concluded both is choppy, which the 660ti is choppy consistently, the 7950 is slightly choppy then spikes occasionally. at the current moment, AMD is looking into the issue, as its something that's not being replicated in everyone's cards.

Nvidia is king lol

The 7950 is king especially at higher clocks, the 192 bit will choke. AMD has been releasing drivers with significant performance increases as of late.

I would go for the 7950 card as it has lots of overclocking headroom to 1100mhz+ @ 1.175V or lower, 3GB is plenty for mods for games like GTA and Skyrim the card also handles MSAA better. When overlocked ask yourself what happens? You get a card faster than the 680 and 7970 for $300 or less, thats something the 660ti cannot touch!

Never going to happen.

worthless review from the UK. So a company sends a sample to a reviewer. I'd guess they sent him THE BEST BOARD IN THE FACTORY.

7950 boost just won the best card for $300 here in Tom's hardware and it is 1 tier higher than 660ti. It also overclocks better. It is a better card. Not dramatically better, but better.
December 15, 2012 7:19:29 AM

I've been extremely happy with my 7950. It's a none boost state card and runs like a dream even at 950mhz. What has been shown in the techreport review doesn't affect my card and the way it delivers FPS. I don't have any lag when showing images. Your also looking at a card which by its specs should outlast the 660Ti through the years.

+1 here for the 660 Ti delivering more consistent performance. Other sites are planning to follow suit with frame latency benchmarking so TR are obviously onto something.

or maybe not?? either way a mild overclock will be enough to trash the 660ti anyway regardless of the 660ti clock speeds.

Always a poor argument. "This card can be overclocked to meet the performance of the model above it! And let's just pretend that the other card can't be overclocked. That will be beneficial to my argument."

Especially when you're talking about a "mild" overclock - i.e. something that could be matched on both cards. At least make an argument for overclocking headroom e.g. "if both cards are pushed to their absolute limits, this card comes out on top".

Level playing field + "mild" overclocks on both sides = level playing field. Not that it's entirely level anyway when frame latency problems are taken into consideration...
