More ram more fps

hello mys system specs
Amd Athlon II X4 635 2.9Ghz@3.4Ghz
MSI 880GMA-E41
Kingston 4Gb DDR3 1333Mhz
XFX Radeon HD 5770 1Gb
Coolermaster GX550
Coolermaster Hyper Tx3

My concerns are over the fps in games like GTA IV ,Assassin Creed 2 etc.
I get like 15-30 fps in GTA IV Medium High Settings(1024*768 Resolution)

In AC2 I get 25+ fps on max settings.pretty decent gameplay.
But in both the games sometimes the game freezes for a second (like 1/10th of a second or like that).
I think My graphics card is defective since it runs too hot 51*C on idle(when doing absolutely nothing).
I am thinking of replacing the 5770 with a 5830(or can i use a GTX 460 on Amd System) and add another 2Gb ram .Or i should change the Cpu to phenom II x4 945 And keep the 5770.
Can I get more fps with that.
Need your expert advise
Thanks

There is no point in adding more system ram as you already have 4 GB which is more than enough for gaming and for 99% of applications. Run performance monitor to see if your CPU is bottlenecking. If it is not look to another GPU but I would have thought the 5770 would do ok.

I live in New Delhi,India and the 6850 have not yet arrived .i can exchange my 5770 for a 5830 (as i replaced 5750 with 5770) but the price of 6850 will break my bank.it will cost me at least 10,000(INR) more

dont upgrade from a 5770 o a 5830 not a big jump in performance and a waste of money. you either want to upgradt to the 6850, 5850, or 6870, i have almost the same exact setup except with different manufaturers and i get great FPS throughout all my games at 1440x900. dont test your computer on GTA IV it was a horrible port, AC2 is a good test. take the 5830 out of the equation.

no matter what you do don't get a 5830, try and tweak your current configuration and run some benchmarks before you do anything

Uhh you might need a new moniter the lower the resolution you use the more the CPU works instead of the graphics card, so i suggest a new moniter nothing crazy can someone else comfirm this?

Check with SMC International. They may have some. It already has come to India. I thill be something close to 12000 INR now as its brand new. But the HD5770 is itself 8500 INR.

Expect street prices much lower than this. techshop.in is way too overpriced.

But i do agree with omgitzfatal, you dont need a new GPU. HD5770 is overkill at your resolution. Would suggest a better monitor first. Get a good LED 22 inch. Then think about the GPU sometime later.

The main issue is the game was poorly converted.

No one was getting outstanding fps'.

The 5770 is MORE than good enough - especially running at 1024x768- I dont know what these guys are telling you. If you buy a higher end card you will have the same fps. If you want to replace your entire system you might get 5 more fps.

My suggestion is everything is fine with your system, turn down the quality settings and wait for the next new game.

Someone really needs to post a sticky about what bottlenecking means. There are a few people that completely misunderstand the concept.

Just because the CPU is the bottleneck at lower resolutions, does not mean that at higher resolutions you need less CPU power. It just happens that at higher resolutions, the GPU also needs to be more powerful. If you go to a resolution that the GPU becomes bottleneck by the same system, the game will be even slower than before, as now the CPU and the GPU aren't powerful enough.

Wow...

Last try, please attempt to follow.

A bottleneck in your system is the process which is holding back the rest of the system. In this case it may be the CPU.

What this means, is no matter how much power you have in the rest of your system, the CPU can only do it's tasks at X speed.

Even if you make the GPU have to work harder by increasing it's resolution, the CPU is still only able to do it's tasks at X speed.

The GPU having to work harder cannot, and will not make the CPU perform faster than it already is performing.

If you make the GPU the bottleneck, that means that it is now weaker than the CPU, and now it's holding back the CPU, which was already not performing fast enough. Now you just slowed the system even more.

If you are running a 32-bit version of Windows, then you cannot add more RAM. It will not recognize more than 4GB.

@op
run 3dmark06 or vantage to see if the pc is working properly and post the detailed scores, though it sounds there is something not quite right... The system seems good enough and rather well balanced, the monitor resolution is a bit small but it won't have negative effect on the performance.

and 51C idle isn't that high really, whats the temp under load? Download GPU-Z, sensors tab will show core temps (min/max as well, just click on the reading it'll switch between the different values)

I would say monitor needs a change because the monitor being used by the OP is outdated. Its more to do with providing the OP with a better upgrade path rather than being on the GTA IV frame rate issue. Which i think most of the people here have already told him about.

I was Thinking of getting a new Cpu Amd Phenom II x4 955 BE but i read article on tomshardware about the difference in performance with the 6Mb of L3 cache
After Reading it i thought that my Cpu is Fine.
BTW when building this Systerm i was on a budget and thought i would OC the CPU but Should get a decent GPU .

if you're editing videos or doing 3d design the extra RAM will make a difference, but it will not increase you fps at all in games.


Just forget about that crap gtaiv already, your system isn't underperforming as the 3dmark score is pretty much what it should.

A higher resolution monitor would help though

Put your HD5770 at 950Mhz 1350Mhz GDDR5 you will get more that 147FPS in 1024x768 the most games they are in 32Bits the 32bits applications don't use more than 4Gbytes ram.

I have 8Gbytes ram dosen't help in games.

Thanks you all who have posted the replies.In the meantime I have searched the internet about the temperature problem that i was facing and noticed that it is quite high and it is probably because of the defective fan since even i put the fan to 100% the temp doesn't go below 46 degree C.So i am replacing the graphic card to get GPU with stable temp.And probably i would change my monitor to a 20" LED monitor from Dell.Maybe then everything will be fine.Thanks for your time.

pretty cool about 20-25 degree C and CPU temp is 25 degree C on idle at 3.5 Ghz and 38 Degree C under load

Have you run furmark 1.8 and prime95 torture FFT minimal length 4096Mbytes together? i'm getting 60 c after the overclock and is a reall problem.

Yes but if is running in stock speed the HD5770 is at 157Mhz and the GDDR5 only in 300hz its 0 watts and the temperature is really high this is no logical for idle mode if he put it in 851Mhz then it goes to 400Mhz and the memory clock goes where he put it. What does he see in the overdrive?

He gave low tempratures for his CPU under load a 40nm GPU 51C idle....

Earlier I had an 5750 from MSI which ran at 40degree C on IDLE

So finally got the Graphic card replaced .I am not complaining but Temp are almost same .But one problem is still there, when cpu is oc to 3.5 ghz a strange error is coming on windows xp.The game stops and error comes.I made a video with my mobile(2 MP camera) but it is not that clear but u can understand what's happening.
http://www.youtube.com/watch?v=LwTz7_TKBs0
When running everything on stock the error is gone but the 3dmark06 score drops to 14245 from 16350.What could be causing this error as the Graphic Card is now replaced .
Could this be a driver issue.Windows XP Updated.CCC 10.10.BIOS updated.

I seen the vid, well, it seems a driver issue, try reinstalling, remove first, run cc cleaner, then re install, latest driver

I dont have a correct CPU temp monitoring tool .But CPU ID HW monitor shows AVG 25 Degree C and load 38-39 C.But i think that These temp are at least 10 Degree C less than the Actual temp .
I would add another fan but over the time dust would be collected all over the parts which is not good .Correct me if i am wrong ,the front fan blows the air in, side fans blows the air in (option for only one side fan but i dont think it is good for The Graphic card as the fan would be directly over the GC) and the rear fan blows the air out.
I have the option of adding a total of 2 case fans.
About the driver issue(the video above) it comes in windows xp , in windows 7 (recently installed) the game freezes suddenly and computer restarts (blue screen error .i think) comes.

I read increasing the voltage could damage the CPU if not then how to increase voltage as there is no option in bios to increase voltage(But it could be done through Control Center ).

About prime 95 is it free on paid .And how to run it to test the Cpu .I would be very thankful if someone helps.Thank you very much.

If you can'y increase the voltage, better decrease the oc, !
Btw, remove the oc, and see if the problem persists, if not, oc till ist stable-
