Will it cause Bottlenecking?

[Ahhlong]

I have a i5 760 with a GTX 650 and I am planning to upgrade to a GTX 760 . My only concern now is that will my CPU not keep up with my GPU and cause bottle necking ? Because recently my friend brought a GTX 760 and use it on a AMD Phenom II x4 and have caused bottlenecking and serious lag during gameplay.

It WILL bottleneck that GPU. Are you overclocked? If not, YES it will. My brother has a 760 at stock clock because his board wasn't very OC happy (long story...), but it bottlenecks his 7950 in a noticeable way. It isn't horrible, and we knew it would going in, but I can say from experience, yes, that type of GPU will be more than the CPU can really handle.

 

How much it will bottleneck, I can't say as it isn't the same GPU situation. If the 760 is the right price point for you, I would still say get it. I don't think it will be a big issue, my brothers 7950 wasn't. It under-performs a bit, but it was a good deal at the time so we got it.

It will bottleneck, and badly but not too badly. I think you should consider selling the LGA 1156 parts and getting an Athlon X4 750K and a cheap FM2 board. an i5-4670K and a good Z87 board. Listen to @{EAC}ShootemUP. He knows what he's talking about!

I don't think it will be "badly". But you will notice it not getting the numbers from benchmarks. It will bottleneck, but nothing THAT drastic to tell him to just go build a new rig. Maybe look into getting a slightly cheaper GPU that will end up performing about the same considering the CPU you have. Its the other camp, but maybe a 7850 is a good, cheap choice that will perform well with that CPU.

Yeah, A 7850 performs well (I've got one) and I feel it would work well with that CPU as well. I was taking a look at this chart and it turns out the i5 760 is actually on the same tier with many AMD chips.

At stock, yes, overclocked, absolutely not.
The i5 760 is a very good overclocker and the performance difference between Clarkdale & Sandy Bridge per clock in games is surprisingly insignificant (5%).

Ever since the i7 Nehalems from Intel CPU performance hasn't improved much, except it would appear as though it improved because of the higher stock clocks.

It is, and it isn't. I have my i7 920 and his i5 760. They aint the same. Granted mine is running at 3.8 ghz where his is stock clocked, but its still not the same IMO. 

Without an overclock, it just doesn't have the speed needed to keep up with new GPU's. But I definitely think a 7850 is a great value to help upgrade your PC a bit. You should see a pretty big improvement in FPS from a 650 to a 7850. Trust me, I am a long time nvidia guy, but right now the red team has pretty compelling value.

Yeah. I'm green team at heart, but what kept me away for my first build was the value AMD cards brought to the table. I will definitely be moving up to a 770 though.

Also, I like to see AMD succeed.

[Guest GRRigger]

there was a benchmark of i5( i think sandy) at it was around 30% increase in minumum fps if overclocked to 4 Ghz and further 10% when to 4.2 ( something like this )

yes, faster cycles definitly matter, thats why we buy unlocked processors

i am too lazy to find bench, but it was benched on skyrim. you must definitly overclock for gaming.

I just slightly overclock it to 3.2 ghz

3.2 will help a bit. But if you could possibly get that up to 3.6-3.8 range you would see improved performance. If 3.2 is as high as it will go or as high as you are willing to go, I think a 760 will cost more than its worth. If you plan on upgrading your rig, it isn't a bad option. The 760 will be a solid card for a while, but if you don't plan up upgrading for a year or two, I would recommend getting a lower performance card and saving that money for something else in the future. Although, if you do want something high performance even though the CPU will be a bottleneck issue, check this out:

Three free games, this makes the price tag potentially a lot more justifiable. If there are three games that you don't have that you want, spending the money on a card that is "overkill" actually makes sense. This is why my brother got his 7950 even though he also has a i5 760. He wanted crysis 3, metro last light, and whatever the third game was. So he basically got a beast of a video card, and 180 dollars worth of free games he really wanted to buy anyways!

[Mr. Expert]

It's all depending on the game. 99% of single player offline games are more GPU dependant but online is another story. No an is good enough gaming chip just OC it and be happy cause that GTX 650 is a slug and you will see much more performance with the GTX 760 in all games except a very very select few like GW2 which perform like shit on any CPU even the best.

so if I really wanted to buy a GTX 760 and not any other cards , would you think I should go for it? And I planning on over clocking to 3.4 ghz

Go ahead. 

I'd recommend a 7950 instead though.
