Hi,

I´m thinking of upgrading my old desktop, but don´t have that much cash to spend.
I was thinking of getting a Radeon 5770, but the thing is, what about the CPU ?

Having that graphic card, would it matter which CPU I choose ? I mean, for moderate gaming.
Would I notice any difference between an i3 and a quad i5 ?

Thanks !

What's your budget? The rest of sys. spec? You monitor res?

Doesn´t matter the budget I guess, I´m not in the US and everything is far more expensive down here (Argentina).

Monitor would be a 22" Viewsonic LED.
Motherboard, probably an Asus with P55 chipset , don´t remember the exact model.
And 4gb ram at first, latter will add another 2gb.


Just want to know, if it would make a difference, between the i3 and i5 if I´m using the Radeon 5770.
Would the i3 be a bottleneck for the 5770 ?


Prices here are much higher than the US, for example, the Radeon 5770 1GB would cost me 240 US dollars.
Core i3 box is 140u$s and core i5 quad it´s arround 250u$s. :pfff:

Well it looks like you're on a budget, so i'd suggest an AMD build with a PII X4 955 and a nice mobo with a 880 chipset. And don't worry 4GB RAM is plenty.

If you can't do an AMD build then yes the 5770 would have no problems with a Core i3 CPU. And if you decide to go for the i5 then avoid the i5 6xx series, i5 7xx are much better.

There´s a 40u$s difference between the PII X4 955 (210u$s) and the i5 750 (250u$s) .

Do you think it worths spending the +40u$s for the i5 intead of the PII ?



Thanks for the replys !!!
Helps a lot.

just wondering how are prices on the gts 450 and the 768mb and 1gb gtx 460?

if the gtx 460 (either one) is not alot more expensive than the 5770, get that.

also ATI 6000 series cards should be released very soon

I would not go for the i5 over the 955.
The i5 is $210 or so, the x4 955 is $140.
With that $60, you can get a gtx 460 instead of a 5770.

GTS 450 1gb is 250u$s, pretty much like the 5770.
GTX 460 768mb is 300u$s and the 1gb version is 350u$s


450 and 5770 are almost same price, you think 450 is better ?

A typical i5 is about 60% faster per core than an i3. An i5 also has two extra cores although most games will not use them. I doubt that you will notice the difference playing games between the two as the graphics card is more important than the processor. However in the future more games will start using the extra cores. It all depends on how long you intend to keep the computer if you intend to keep it more than two years get an i5 otherwise get an i3 and spend more on the graphics card.

A "typical" i5 is the 6XX dualies, which is just a i3 Turbo.
Your conclusions are only true for the "special" 7XX series quad.

I was thinking of the i5 760 as being typical of an i5 processor and it would be the processor I would buy if I wanted a i5 processor. The "6xx dualies" can be disregarded in this discusion.

Hey, thanks for all the replys.

I think I´ll try to go for the i5 750.

And the video card... somebody said the 6 series are going to be released soon.
Maybe if I wait a bit, prices on the 5 series will drop, and be able to get some card better than the 5770.
Or some 6 series for the same price as the 5770.


And about Ciudad del Este... that´s pretty far, and also very untrusted.
They sell lot of stolen stuff, you don´t have any guarantee and... well... I think that´s enough. :lol:

Yes or wait and get the GTX460. ;)

Why get the i5 750? The i5 760 is a little bit faster at almost the same price.

he wouldnt notice the difference.... 2.66ghz vs. 2.8 ghz
only if it is a little more expensive get the i5 760, if not get the 750.

I will never go for the intel when tight budget is involved I always go for AMD.
