Will my CPU bottleneck HD 5770?

[masternik]

hello ! every body ... i was willing to buy 5670 a week before but now i have got budget to buy HD 5770 1 gb ddr5 .
So i need help that will CPU be able to support the GPU?

USAGE FROM MOST TO LEAST IMPORTANT: Gaming [ All latest High end Games on high settings], home theater/watching movies)

CURRENT GPU AND POWER SUPPLY: ATI Radeon HD 5770 and Cooler Master 460 W PSU

OTHER RELEVANT SYSTEM SPECS: CPU: E6550 Core 2 Duo 2.33 ghz
MoBo: Asus P5QPL-AM
memory: 3 gb ddr2


OVERCLOCKING: No

MONITOR RESOLUTION: (1400 x 1050) or (1024 x 1280)

No that will not bottleneck the CPU. If it were a 5850-5870 at a resolution of 1680x1050 or higher than it would bottleneck because then it becomes a CPU battle.

^Actually, the higher the res, the more gpu dependant, so at his lower res, it actually relies more on the cpu than it does on the gpu, your thoughts are reversed.

I'd say it will bottleneck but shouldn't be too bad, maybe 15% less performance than it should, It'd definetly help if you OC your CPU to at least 3.0ghz which should be pretty easy, OCing is safe as long as you don't put too much voltage and keep things cool.

If it can handle a 9800gt or a 3870 then the answer is yes but I still suggest that you overclock the cpu.

5770>>>9800gt/3870

will my mobo support oc ?

 

[masternik]

and once u oc the processor then u can't get it back to stock? am i right?

 

[wiinippongamer]

You can get it back to stock anytime, and yes your mobo supports OC, you will need a new cpu cooler though. This will serve: http://www.newegg.com/Product/Product.aspx?Item=N82E16835103065

and one more question plz ..... when i oc to 2.8 or 3.0 ghz then will i get 100 % of the GPU ?

 

[masternik]

or if i upgrade to e6700 2.66 ghz then is it good ?

 

[Soma42]

Well I can't say you'd automatically get 100% if you overclock it, but as a reference I have a e6750 overclocked to 3.6 GHz and only on heavily threaded games (3 or more) is my CPU not enough. But that said, I'm hopping on the Ivy Bridge train next year because it's not enough for me.

If you get it to 3.0 GHz then you'll be good enough

The way to check is when you are playing a game and open your task manager and see if your CPU usage is at 100% or not. If it isn't then your GPU is being fed as much as it can handle.

Edit: Above is a bit of a generalization, but it's true most the time.

 

[masternik]

Thanks to every body on this thread who helped me out ..... ! i m gonna get e6700 and oc to 3ghz and hope it gets me enough .....!

I think a new CPU will help you a good deal, but look at the e8500 and e8400 instead of the e6700, as they are clocked at 3.0 GHz and 3.16 GHz and would overclock to 4.0 GHz with not much difficulty.

Edit: Looks like the e6700 is clocked at 3.2 GHz, but I would still recommend the e8400 if you can afford it as it has a higher FSB and a larger L2 cache (helps with gaming a lot in the 775 chips). Try ebay maybe for a lightly used one.

Frankly, the socket 775 is dead and you would do best to upgrade to Sandy Bridge with a dual core i3-2100 or a quad core i5-2500k, but that may be outside your budget...

 

[wiinippongamer]

Upgrading old hardware is not a smart desition, you should stick with what you have and OC as far as stable, the e6700 is pretty much an overclocked version of the e6550, if you OC the e6700 it will be the same as your e6550 at the same clock rate (3.0ghz.), so you'd be wasting your money if you do that

I agree, but your signature is evil... now I have a fingerprint on my screen, thanks!

Haha yeah me too... Thought I kept missing it until I saw two of his posts on the screen

 

[masternik]

well thnx to all experts.... u really helped me alot ....!
its done icouldnt get e8400 or above but i got a e7300 lightly used at same price as a new e6700 costs and it works flawlessly with hd 5770 ....... no need to oc !
