Will the E7400 bottleneck HD 5770?

I already have Core 2 Duo E7400 (2.80 GHz), 4 GB DDR2, and G31 motherboard. I am considering buying a video card, any want to ask a question: Is it worth it to buy HD 5770 or it will be bottlenecked by my E7400 so I have to consider a slower video card? And if the HD 5770 isn't appropriate, what card would you suggest instead?

I can't overclock my CPU (my motherboard does not support overclocking), my screen resolution is 1440*900).
I prefer a card with low power consumption and low noise.

Thank you.

Yes it will be bottlenecked by your cpu....try out a 5750....i have a e7300 overclocked at 3.22 ghz..so the hd 5750 will be a perfect match for you....

What is your motherboard?

Those two should be fine.

The current price difference between a 5750 and a 5770 is like $15. Just get the 5770 so when you do eventually upgrade your CPU/Mobo then you won't be as bottle-necked by your video card.

Certain games are more CPU limited than others anyway. There are many games out there in which you will see higher framerates with faster video cards even with your Core2Duo.

if not less, the 5750 needs to drop in price

i wouldn't worry much about bottlenecking your cpu with that video card. the C2Ds at high stock speeds like the e7400 perform very well in most games. but if you're only gaming at 1440 x900, then a 5770 is a bit overkill. you'd be fine with a 5670. however, if you're fine with spending the extra money, the 5770 will still be an excellent choice if you plan on upgrading your monitor and/or CPU

There will not be a bottleneck at all. Its fine. the 5770 isn't a high end GPU and a E7400 is not a weak CPU. Even if there was a technical restriction it would be minimal and you wouldn't notice it at all.

+1 to mactronix. I don't think you'd see any noticeable bottleneck. I'd be more worried if you had some lower-clocked quad, rather than a relatively higher-clocked dual.

Get the HD5770, totally. You'll love it.

Your CPU won't bottleneck the card as others said :)

Thank you, what about if I upgraded the CPU to Q9400, will it be noticeably better?

Depends on what you are wanting to do with it really. This is good for checking out and comparing the different merits of differant CPU's http://www.anandtech.com/BENCH/DEFAULT.ASPX?B=2
They dont have a 7400 but if you compare a 7500 and the Q9400 you will see that in some games it actuallt looses to the 7500.
Your 7400 isnt exactly a country mile differant to a 7500.

You don't need to upgrade that E7400.

Your RIG is enough for 1440*900 resolution.

In fact HD5770 is an overkill for 1440*900.

Hi , im using the e7200 at 3.0ghz with a HIS5770 at 1920X1080 with no lags\bottlenecks or any difficulties! So you should go for the 5770 rather than a 5750.

Definatly go for the 5770 if you can afford it and plan to keep it for a while.
Anything lower down i would expect to struggle with a full blown DX11 game, if we ever get any that is.
Some say that even a 5770 may struggle and for sure we are only guessing at this point but personally i think a 5770 is the lowest you should consider if you are wanting to use DX11 in the future.

What resolution do you game at?

That processor won't bottleneck much if it is overclocked past 3.5Ghz.

You'll get play-able performance with that CPU.

the screen im using is 1600 x900, i will try eyefinity with two other similar monitors every now and then.
my pc is direct from hp, and i have heard that overclocking cpus when they come prebuilt is a very bad idea, any truth to it?

HD 5870 is a big big overkill for games at 1600X900(I play on same resolution).

Get a HD5770 or at most a HD5830.

i know, but im thinking what will be more future proof, and the possibilty of upgrading my monitor.... i was orginally going to go with the 5830 but before i knew it i had saved 400+, researched for about a month and narrowed it down to the 5850 or 5870. What are you using????

I'm using a 9800GT(1 year old). I'm just a casual gamer.


Whatever you get just check before whether you can OC your CPU or not.
