Title: Will my cpu bottleneck my gpu I: ?
Post by: A4F| Ghost on September 17, 2011, 05:43:36 AM
Hey guys  :)

my current pc specs are :-
core 2 duo e4500 2.20 ghz
4gb ddr3 corsair ram
Asus P8H61 mobo
400 watt psu with the gpu 6pin connector connector

and im gonna buy a gtx550ti in a couple of days , so umm will my cpu be bottleneck my gpu ?
if yes than will overclocking it to 2.60ghz help ?

ill be buying a sandy bridge i5 processor next month so im gonna need a temporary solution

Thanks

anything dual core these days will most likely bottleneck on newer games

Yes, it will "bottleneck". Also Overclocking will help out. Though play it safe, rather bear with low fps than frying your CPU.

Also, is that PSU good enough for both I5 and the new card? I'm not good at wattage couting.

getting the 2500k... goodman, goodman. if its only a temp solution, youll be fine, but it will tend to bottleneck

@azi im gonna get a new psu when i get that i5

Anyway how does an ati 5670 perform when it comes to gmod bfbc2 etc
cause i also need to get some other upgrades such as a casing and a new led and was thinking of getting the 5670 for now

Meh nvm im getting the gtx550ti not the 5670 anyway thanks for the help guys , will oc my cpu when i get the gpu to 2.60ghz while keeping an eye the temp

what is your heatsink/fan?

The stock intel one, dont worry about that ill get an awesome cooler master one when i go buy my gpu

Anyway thank for the help guys

the vortex plus or maybe the Hyper N520

Yeah it will bottleneck a bit. Try to get a quad core at least.

Also for that graphics card I think 500w would be better but 400 will work.

So long as it's a 80+ 400W it'd be fine

cheap shit though, and it'll pop

In all honesty,

No.

Your CPU will not significantly "bottleneck" your computer if all your doing with it is playing games.

Do not listen to these people and their quad cores! (Yes quad cores help in many ways, but isn't the most economical route to having fast games)

The performance difference between having. An i7-990X Extreme edition ($1000) and a i3-2100 ($124) is 30%. So you will see a ~30% fps increase in gaming performance, for an 806% increase in price. While you are not making the jump between these components, it illustrates my point.

Since you are upgrading your cpu anyway I just flat wouldn't worry about it.


In my books you overclock your components for two reasons:

A. You enjoy a challenge so eeking every bit of performance out of your components.
B. You are suffering from insufficient performance and don't have the money to upgrade.

While looking at your... temps... is important, in the cpu's case you generally never approach the thermal design limits of your processor unless you have a really poor cpu cooler.

You should look out more for erratic behavior of your computer. I could cool my computer to -100 F and there is still a point where the increased frequency will destabilize my computer, cooling it better definitely helps you reach higher overclocking potential, and it is also very bad for your cpu to run at 90C, but chances are you will suffer from instability before temperature damage.


As for Quad vs. Dual.

In games, in most cases you will not see a large difference in performance going from Dual to Quad. In every day tasks you will definitly see an increase in your multi-tasking. But always go for a Dual core with the individual cores being fast, before you go for a quad core with slow individual cores.


BUT XRAIN!!?!?!?!!! A FASTER PROCESSOR WILL PROCESS MY GAMES FASTER!!!

Yes you are right, but there are other things that will increase your performance MORE for the same cost. (This of course changes depending if you mostly play games or do photoshop/CAD. But I'm assuming you mostly want to play games)

Lets look at the tasks that each component has in your average game.

CPU
- Positioning Computation
- Tells the GPU how everything should look
- The millions of minor tasks making everything work together

GPU
- Renders a Frame according to instructions from the CPU

The CPU's task is indeed complex, but on the whole isn't very strenuous. While the GPU's task is simple (relatively) but there's a crap ton of it to do, the cpu can only issue instructions as fast as the GPU can render the scenes.

So in the case of games, unless you have a very high end GPU, you can get away just fine with a somewhat underpowered CPU with a stronger GPU. Note however, you will probably suffer in all other areas of your computing other than games, but if you find it's performance sufficient out of games, then all you really need to do is upgrade your gpu and you should be just fine.

Well said Xrain.
I was about to post, but too many people pointed it out already.
The 550 is not nearly fast enough to render your core2duo a bottleneck.

Damn xrain, all that to tell him he will temporary have a slight bottleneck? You scare me ._.
Though he already said he was getting an 15 SB, so i assume he is getting 2300 or 2500k... which are both good
I agree with xrain, go buy a 2100, maybe 2300 if you dont mind the extra spending, if youre just gaming, or if you need to do something more intensive and have the spare cash, wait for the ivybridge. Supposed to be 20% more power, but hell if I know what the price will be.

Thanks for the response xrain
anyway ive got everything planned out , thanks for the help guys.
