View Full Version : Does it bottleneck the HD4870X2?
03-24-2009, 01:21 PM
Wow...it's been a looonnng time since I posted my last thread here. And because of that, I forgot my old password! Lol. I am a member by the name Lucky_Luke and this is my new username. Hope you guys still remember me. Anyway...I've got a qn to ask you ppl.
I have been using the GPU HD4870X2 for gaming for several months. Basically, the framerates have improved ever since the latest GPU driver's installed. However, I still feel that the GPU hasn't performed its best performance yet. My current CPU is the Intel Core 2 Duo E6550 at 2.33Ghz. Here are the remaining details :
Motherboard : Asus P5GC - MX/1333, LGA775, FSB 1333(OC)/1066/800
RAM : 3Gb @ 667Mhz
PSU : CoolerMaster @ 750W
Monitor : 19" LCD Max Resolution at 1440 X 900
OS : Vista Premium
My questions are :
1. Do you think the CPU really bottleneck the GPU?
2. What is your recommended CPU if it bottlenecks the GPU? Don't overclock it pls. (LOL)
3. I have been considering about the latest CPU innovation by Intel which I believed everyone should know by now. Yeah, it is the i7 CPU. Would anyone please give me some idea how well is the architecture and performance of this latest CPU as compared to Core 2 Duo. Does it really worth the money for graphic-intensive gaming like Crysis my fave. FPS game?
Thanks for your valuable feedback,guys! =)

I think it's more of the monitor limiting the GPU rather than a CPU bottleneck. Your monitor's max resolution is still quite small for your 4870X2.

Actually your CPU is indeed a bottleneck... at this point the i7 is pointless , because like nearly all games , Crysis doesn't make much use of 4 cores .
I'd suggest an E8400 and overclock it... but then again you said you don't want to overclock , so then you should get an E8500 or E8600 ( basically the same CPU , just clocked higher ) .
And yeah that monitor is WAY too small ... you could get a much larger monitor (1920x1200 24" or 1680x1050 22" ones) , and play games without any prob at those resolutions .
I have to disagree with Radiator on your first question. The CPU isn't nearly enough of a bottleneck in gaming performance to justify a new one yet. It is indeed a limit in your system along with the RAM, but buying a new CPU isn't worth it just yet in my opinion.
If you do choose to upgrade, then I would agree with Radiator that the e8500/e8600 is the route. I would also suggest the core2 quad 9xxx series for that socket.
The i7 is indeed a powerful CPU, I just built a system with one and got the chance to test it out a bit. I was... impressed. Very impressed. Right now it does indeed beat out the high end core2 quads, but it's only by a little bit. When Games start taking advantage of even more threads then it will really shine. Running UltraFractal at 10 or more layers of fractals with 1000+ iterations and heavy anti-aliasing gave me no troubles at all, rendered overnight.
Unfortunately it requires a whole new motherboard and RAM. Neither are cheap yet.

Dependant on the game , the current CPU CAN be quite a bit of a bottleneck .
And by the time the majority of games take full advantage of 4 cores , I'm sure there'll be much better CPUs out at the same cost as the current i7's .
But yeah there's no doubt that the i7's are REALLY good , once you take full advantage of them .
Another example is GTA IV :P . A massive performance difference between an E8500 and an i7 ( 30 FPS vs 60 FPS ) on a HD 4870 and 1680x1050 as far as I remember . Then again GTA IV is poorly optimized ... but I've heard great things about the latest patch , which apparently made it very smooth to play , on just about any high-ish end machine .

There's THAT much of a difference??? Is GTA IV utilizing 4 cores?
03-26-2009, 12:11 AM
it has to
otherwise why would it be that different ?
some other games that use 4 cores
far cry 2
supreme commander (and thats an old game now)
i suspect by end of this year a lot of games will use more than

Yes . If it was properly optimized it would run great on 2 cores aswell considering the engine and graphics , but it's just a worse than lousy port .
Then again I've been hearing good things about the latest patch ... that people have gotten it running smooth on dual cores .
Personally, I think it's the hyperthreading giving 8 effective cores on a single chip with an excellent cache system and an onboard memory controller that gives it all that power, but maybe that's just me. ;)
...Seems unfair that AMD did that kind of quad core design first...
Seriously though, GTA IV is a pretty bad example for PC hardware. If you're looking for future proof then yeah, the lower clocked quad core is going to beat out the e8500, but right now most games will do better with one or two threads at a higher clock speed.
If you have an LGA775 motherboard already I'd say stick with it, it's not worth it for a new motherboard with an i7 and all new RAM. If you choose to upgrade to a new CPU, just get something from the q9xxx series/e8xxx series.

I brought in GTA IV , because it currently is basically the only example of where quads ACTUALLY make a difference .

Hmmm. This is interesting. I'll have to try this out on my buddies i7 build once we get it put together this week. He's trying to hackintosh it (god knows why), but I'll see if I can talk him into a dual boot.

Light Emitting Diodes, popularly known as LED lights, are small devices that are which you can use everywhere over the lighting. Compared to understand more about several tools all of these are you can use to explore generate light and portable,going to be the Light Emitting Diodes weren't that common before the energy crisis. Since the homemade solar power system crisis,much more and a great deal more people are searching and then for each and every alternative that can be the case which can be used for more information regarding save homemade solar power system and be capable of getting going to be the maximum keep using about about when you need that use homemade solar power system LED light in weight light bulb replacement is that also considered as an all in one potential alternative to educate yourself regarding many other over-all hardly ever just any sexual affair involving energy usage.

More in all probability than rarely ever,about whether or not all your family are a DJ and are playing everywhere in the stage,you would likely prefer going to be the audience in order to get capable concerning seeing all your family members Nightclubs and several other places generally will be dark,therefore about whether or not you have to worry about for no reason have any stage lighting,all your family members never ever among the most not only can they hardly ever be the case capable of seeing what all your family members are performing if that's so,going to be the lot of people may or may not have a multi functional tough a period enjoying which of you is the fact that playing the creations they are dancing to educate yourself regarding Vast majority having to do with DJs gps device to learn more about add stage lighting to explore their gear. Stage lighting differ upon designs effects, and differ on the interest rates There is sure marketing campaign an all in one stage light weight to learn more about fit any performers budget. >
