GTX 760 + core i3 2120 = bottleneck ?

Hello

I am thinking of probably replacing my old GT 640 for a GTX 760, (Upgrading for next-gen).
Now I'll list my pc rig:

core i3 2120
Nvidia GT 640
crucial 4GB DDR3 RAM @ 800MHz (Upgrading to 8GB)
Some MSI motherboard
XFX Pro core edition 550w (One of the best PSUs I have ever used.)

Now I am aware there may be a slight bottleneck @ 1080p and at ultra settings, but would it be noticeable? I will upgrade to a quad core during Christmas time.
I play games and will play games like:
Battlefield 4
Assassins creed 4 (When it is on sale)
Borderlands 2
borderlands 1
GTA 4 & 5 when it comes out
Chivalry: Medieval warfare (I play this a lot!)
Civilization 5
Most source games
Skyrim and TESV: ONLINE when it comes out.
Assassins creed 3
Battlefield: Bad Company 2
Dead Rising 2

Any help would be appreciated.
Cheers.

Setting higher Graphics and resolution will make your CPU LESS of a bottleneck... Lowering your res will make it more of one. So say your CPU can only provide you 30 FPS, but you have your graphics turned up really high so your GPU can only provide 20 FPS, so now you are getting 20 FPS with a GPU bottleneck... Now if you turn your graphics on really low your CPU can still only provide 30 FPS but now your graphics card can provide 100 fps so you are stuck at 30 FPS with a huge CPU bottleneck.

Some games are more CPU intense than others... For the most part you will not have to much issue with CPU bottleneck but is some of the games such as BF4 multiplayer you might see some low FPS spikes due to a CPU bottleneck.

explained easily: The cpu will bottleneck the card hard. and for bf4 and games like such they are starting to advantage 6 cores and you have 2 cores. you may can play on low with no stutter but if you higher it will be not good experience.


What? That is not what i said at all. His CPU will be fine in most of the games he listed and will run BF4 decent as well, with some cases in multiplayer where he will get low FPS spikes - all will be playable.

i know you didn't mean it but that is the truth. you will not have good time on high graphics. and the cpu will run maxed out always which will make the life time of the cpu much less.


What are you talking about? High graphics won't make your CPU work harder it will make your GPU work harder... That has nothing to do with increasing the CPU bottleneck.... in fact as i explained before raising the graphics will cause the CPU to be less of a bottleneck (although FPS might drop some).

The CPU might bottleneck, I really don't see why people are saying it will bottleneck like hell...
Here : http://www.anandtech.com/bench/Product/102?vs=289&i=27....

I have the Phenom X4 955 3.2Ghz and I will be able to run with very limited bottleneck if I OC my Phenom.
You can do the same, you will just have to do your best to get the max OC out of your i3. You will have bottleneck, and yes, the 2 cores certainly won't benefit you, but you will be able to play normally depending on the game. You should try to look into buying a new CPU soon though if you are planning to buy the 760.

BF 4 would run a lot smoother on a quad core +, but don't forget that battlefield 4 is one of the most demanding games atm...

yeah overclocking the cpu would help and wouldn't bottleneck as much and sadly the i3 2120 is locked so you cannot overclock it.


Ah, I see now ! ><

Well, the bottleneck won't kill him :p , if he can buy the CPU in the next couple months, he should be fine as well. It will increase performance anyway, no doubt. Only the 760 won't be able to show its full potential yet =)
