Will my cpu bottleneck a GTX 460?

Hi
After some help from you guys, i decided that the GTX 460 1gig was the new vid card for me. When I went to my local shop to pick one up, the employee told me that my cpu might bottleneck the grapahics card. I'm using a Intel Core2 Quad core 2.4gz processor, which i thought was a fairly fast processor. Will i not get the most out of my new card with my current processor? Thanks.

Which model? Q6600? Most Core2Q's can be OC'd easily to 3.4ghz.

I'm not sure what the model is, is there a way of checking?

Download CPU-Z (google).

Or go to Start -> My computer -> System properties.

Download and run CPU-Z, then post the information here in this thread.

yes it will be enough for the gtx 460 i think but still oc can be good to unleash the real power of the gtx 460...

I'm not sure i can oc my processor due to the fact the system was originally built by HP. I was just looking at my bios and the settings that I can change seem to be fairly limited.

no problem man still you have a good cpu and you will have an good gpu...i.e gtx 460...
so don't worry you are going to enjoy your games as you expect..

Your CPU is still perfect for most games and is not a bottleneck for your GTX460.
Despite its age, the Q6600 is still good and it can be o/c as you wish.

I'm not sure where these people are getting their information, but I couldn't stand for you (OP) to be misinformed and wonder why your games will run slow.

I have a q6600, and at stock speeds of 2.4GHz IT WILL/DOES bottleneck my GTX 260.

You will lose alot of performance (compared to what you could have), with a stock q6600 and GTX 460.

If you want it stop being a bottleneck, you'll want a OC of 3.0GHz for gtx 260, so probably 3.2-3.4GHz for GTX 460.

If you have a pre-built PC, your probably SOOL... :cry: 

Even from my personal experience, if you still don't believe me, when you get that GTX 460,
go run some DX11 games (or mostly any game that is less than 5 years old) and
turn graphics all the way up.
Note your fps.
Now turn them all to medium settings.
Fps will not change by much at all.
(If you turn them to bare bottom settings, you will gain noticable fps, becuase your cpu can probably keep up with those settings.)


On a happy note: Your GPU is being bottlenecked becuase it is a complete kick-@ss card! Next time you go for a performance upgrade, instead of buying more RAM or something, just buy a good mobo and OC that thing.

kennyparker, thanks for the advice, now I don't know who to believe :)  My biggest concern is spending a fair amount of money for a card that I couldn't fully take advantage of.

for me ?

The problem with the Q6600 is that it has a low base speed and most games still don't use more than 2 cores. In those games your processor is basically the same as a dual core at 2.4ghz which is passable but really not very good. So to answer your question, yes, it will bottleneck the card but not always. It will depend on the game as well as a number of other things like your resolution and settings you are using. The higher the resolution/settings the less likely your CPU will be the limiting factor.

Your processor has a much higher stock speed and your motherboard should also have no problem OCing that CPU up to 3.5ghz even just on the stock cooler. At that point you really shouldn't have any issues at all.

What cadefoster's limiting factor is really the locked OEM BIOS in the prebuilt HP PC that doesn't allow the Q6600 to be overclocked.

Is the power supply in this prebuilt PC capable of providing sufficient power to the GTX 460 graphics card?

The Q6600 is bottlenecked by its low clock speed..sheesh.

I have confirmed this.....

I have a Q6600 stock speed with 6GB RAM. I removed my 4870 and stuck in my new GTX 460 and didn't get a single frame extra in any game. This tells me that the 4870 was not even maxed out and now the 460 is not even breaking a sweat.

Sigh I will play with overclocking at least to 3.0Ghz this weekend but in reality my PC is near 3 yrs old so a new mobo and powersupply and RAM are needed, basically a whole new PC. Can't do that until next year so will have to OC the crap out of my Q6600, will look at better cooling as well to buy some time.

sorry about re-opening this thread but i have 2 core 2 quads. a Q6600 and a Q9400. im looking to run 2x 460's in SLI and was wondering if i OC either of these to about 3.6GHz on Liquid would i still be running into a bottleneck?

You are looking at a tough task but it can be done if what you is good enough. At stock the q6600 won't be enough while in sli the gains are not going to be a great as they could have been. One way to test to see if the system can take a second card is to already have one of the choice cards and something spare like a old 8800gt. Dedicate the 8800gt, if every thing goes well you will not see any fps loss in games that don't make use of it and games that do will see a nice boost. If there is a big loss in some games then you found a bottleneck. Any way you need to bring that q6600 to at least 3ghz while the other the most that you can.
