The GTX 650 Ti Boost is a GTX 660 with one SM disabled, meaning it has less unified shaders and texture mapping units.
The cards run at the same clock rate and have the same memory interface.
You could over clock a GTX 660 as much as a GTX 650 Ti Boost so the GTX 650 Ti Boost can never match the GTX 660.
For real world differences, here is a benchmark:
http://www.tomshardware.com/reviews/geforce-gtx-650-ti-boost-gk106-benchmark,3463-6.html

The GTX 650 Ti Boost was a good value card when it was released.
If you are considering this card, make sure it is the 2 GB version.

This is off a little but, overclocking really doesn't help the 660 but the 650 ti boost it does.
The 660 is already gpu system limited,everything lines up well all the way(shaders gpu memory) around this was also the case for the 5770 from ATI. Everthing is balanced overclocking the 660 does not offer good results due to memory interface dealing with the attached shaders and gpu. The 650ti boost however does benefit a little more due to the disabled parts on the boost which is a chopped 660 anyway, Increasing the clocks does offer a more noticeable improvements vs the 660 as overclocking makes up for the disabled parts on the 650ti boost.

Either way, overclocking gpu's generally nets less than desired results until you get into high end cards or absolute freaks of midrange gpu overclocking (7850/4870/gtx460)

Op you likely won't make up the difference no matter what you do overclocking wise.

I always get a laugh out of your posts. Do you just make this stuff up as you go?

Why do you think that a GPU with one SM disabled (the GTX 650 Ti Boost) would somehow be more over clockable? They are the same chip. When they came out of production the chips used in the GTX 650 Ti boost had a faulty SM so they simply disable it and sell it as another model. You can increase the GPU frequency and memory frequency of either card in exactly the same way.

well how much should i overclock the core and memory frequency of a TI boost to match a gtx 660 at default/factory settings?

and between a 7850 and a ti boost? forums here on tomshardware always say that a ti boost is slighty faster than a 7850.

Yes it does......
Disabled parts usually mean less heat(higher clocks). On gpu's like 660 this where the card itself is well balanced. Additional memory bandwidth due to less input from the shaders does allow for the overclock to be more effective and make up more performance more than the 660 can due to its already saturated memory bus. Point being the 660 is already addressing the memory bus in full or a close balance, removing some of the parts does allow the overclock to be more effective.


Also did you see the article about the coming 285(x) is coming, I was right there too.

OP I say just get a 270 instead for the same price as the 650ti boost with better performance If you insist on getting nvidia, for the 750 ti there are versions with pci-e connector which overclocks quite well.
Here is a link for the 750ti vs 650ti and without the power connector and overclocking it performs a bit better

Cheap models are had for 129
I wouldn't mind the fellow above, he's been hounding me yet doesn't seem to know why i am wrong only that I am. You'll see a lot of that happening from people who know what they read online. Not to say the person wasn't trying to help he just can't in this situation.

The HD 7850 and GTX 650 Ti have very similar performance:
http://www.tomshardware.com/reviews/geforce-gtx-650-ti-boost-gk106-benchmark,3463-6.html

You will only get very small gains from over clocking. It really isn't worth the risk of destroying your card in my opinion.
Are you planning to buy these cards second hand? They haven't been manufactured in some time.
The AMD Radeon R9 270 mentioned above is the current model from AMD replacing the HD 7850, with slightly higher performance:
http://www.tomshardware.com/reviews/radeon-r9-270-review-benchmarks,3669-5.html

From Nvidia, the GTX 750 Ti is slower than these models and the GTX 760 is faster:

Sorry if I was rude before. You have explained what you were trying to say better here and I can see there is some logic to it.
I can see two valid points you have made:
The GTX 650 Ti will achieve higher clocks because it generates less heat.
The GTX 660 will benefit less from higher clocks because it will be memory bandwidth limited.

I'm not sure that the second point is always true, but it could be in some applications.
These things may mean that it is possible to narrow the gap between these two cards through overclocking, but the GTX 650 To boost overclocked will still never be as good as a GTX 660 overclocked.

I wouldn't have used the term "memory bus" in your description. Memory bandwidth would be better. The effective memory bandwidth of a card is effected by the bus width, memory speed and the compression used. There are too many stupid comments being made on the forums about the width of a memory bus in relation to the total VRAM or the memory bandwidth. The memory bandwidth and total memory (VRAM) are independent. A card can achieve the same effective memory bandwidth though better compression and faster memory with a narrowed memory bus. This is the case for the Radeon R9 285, GeForce GTX 970 and GeForce GTX 980. You can avoid being confused with these people by using the right term.

I'm not sure what your comments were about an R9 285X. I would go back and read them but I have commented on hundreds of threads and couldn't possibly find the one you mean. If you do have a link to the thread, I would be happy to re-read your comments.

i think i got myself a nose bleed after reading that,.. memory bus is the 192 bit right? so the higher the bit the easier it is for data to travel from gpu ram to gpu core?... if i could overclock the 650 ti core clock and memory clock as high as the default 660 ti would it performance be the same? of not then i should just leave my ti boost alone then.

im only running at 1680x1050 anyway and games like crysis 3 play smoothly at ultra high x16 af smaa x1 aa

Despite our disagreeing im sure that both of us will clearly tell you the 650ti and 660 are parts that can be outperformed by cheaper components. I don't even see the 650ti boost for sale anymore. If you want 660 performance, go get one. I wouldn't count on the 650ti boost matching the 660. Yes it is possible to reach that performance level with the 650ti boost but not probable.

As for crysis 3 ultra high no not likely at 60 fps but it should be playable providing you accept a few things must be turned down.

It would have been worth mentioning in your original post that you own the GTX 650 Ti boost.
This card was a good mid-range card when it was released.
You will be able to play Crysis 3 with medium to high detail with 2x SMAA.
Here is a benchmark at 1920x1080:
http://www.tomshardware.com/reviews/geforce-gtx-650-ti-boost-gk106-benchmark,3463-4.html

"Very High" is the highest graphics setting in Crysis 3. This will be unplayable on your card.
If looking at a new card, I would suggest the R9 280X as a minimum worthwhile upgrade.
The GTX 970 is substantially faster again and would be worth the extra money, not just for this game but for other games released in the next few years.

well i'm playing crysis 3 with this card at 1680x1050 ultra high preset x16 af and smaa x1 low aa
from 30-50 fps really, i'll make a video if you like. finished it twice already - also in the jungle level its really smooth like 40-50 fps dropping to 30 fps when explosions happen.

also others games like COD MW3 1680x1050 all maxed (50-60 fps), skyrim all maxed out (50-60 fps), nfs rivals all maxed out (50-60 fps).

pc specs
procie : core i5-4460 3.2ghz - 3.4ghz turboboost
ram: corsair vengeance 8gb 1600 cl 9-10-9-24
gpu: msi gtx 650 ti boost 1gb 192 bit gddr5
mobo: msi h81 something
psu: 450 watts true rated psu sleeved

If you are happy with your card, you don't need to do anything.
It's unusual that you have a brand new CPU and an older graphics card.
If you did want to upgrade your graphics card, you could run the GTX 970 or GTX 980 on that power supply (assuming it is good quality), but not the R9 280X, R9 290, GTX 770, GTX 780, etc.

well i'm thinking about a r9 270x if i could sell my old card. the card is about a year old and the procie is about a week old :D

hmm can run on 450 watts gtx 970 but not gtx 770? about a gtx 680?

its a powerstation2 450 watts full sleeved true rated psu.

I can't find any information at all on your power supply, which is not a good sign.

GTX 650 Ti boost - 134W, you require a +12V rating of at least 28A or 330W
R9 270X - 180W, you require a +12V rating of at least 32A or 385W
GTX 680 - 195W, you require a +12V rating of at least 34A or 405W
GTX 770 - 230W, you require a +12V rating of at least 38A or 450W
R9 280X, GTX 780, R9 290, R9 290X - 250W, you require a +12V rating of at least 40A or 475W
GTX 970 - 145W, you require a +12V rating of at least 29A or 345W
GTX 980 - 165W, you require a +12V rating of at least 31A or 370W

The GTX 680 is now two generations behind. I don't know where you would find this card new.
I have listed these cards in order of performance rather than power usage.
Notice how efficient these new GTX 970 and GTX 980 cards are.
If it were me, I wouldn't be risking your new components on this power supply.
Have a look at any XFX 550W model you can find, they are all good.
Rosewill Capstone 550 or Antec HCG 620 are both also good.

Power supply doesn't specify the combined rating for the two +12V rails.
You are currently running the GTX 650 Ti Boost, so you would probably get away with the GTX 970.
Minimum worthwhile upgrade with an AMD card that I would suggest would be the R9 280X, but this would definitely require a new power supply.
Rule of thumb is at least three tiers in the graphics hierarchy:
