CPU vs. GPU (Gaming) how to upgrade

Hi guys,

I just built a new gaming rig;

Amd Phenom x4 965 BE
Radeon Hd Ati 5770
700 Gb WD black
AC Freezer 7 Pro Rev.2 92mm
ASUS M4A785TD-V EVO
8 GB 1600 Gskill Ram

And I'm not getting the performance I'd hoped out of it. It runs games fine but, I'm not getting the frame rate, I'd like.

Both the CPU and the GPU are as overclocked as I'm comfortable (CPU=17.5x) (GPU = 900 MHz GPU clock and HPM clock 1395Mhz)without changing the cooling system.

Do I upgrade to an intel i7 860?

Do I go to water cooling?

Do I get another 5770 and go cross fire?

Whats most cost effective way to upgrade?

Probably another 5770.

you should have gotten a 5850 and only 4 gb of ram
i recommend you sell your 5770 and get a 5830 or 5850

Sell the extra 4GB of your RAM and buy another HD5770, it will be a very good trade of for performance.

many games don't support xfire so a single card would be better

Yeah my worry about crossfire is that its so driver/patch dependent.

Just to piggy back on what the others said.

The answer to your problem is a 5850 or 5870 Gfx Card. Sell your 5770 to a friend.

On a side note, what type of temps are you getting with your Heatsink on your 965 BE?

I am getting rid of mine, because it performed on par and sometimes worse than my stock Heatsink on my 955 BE.

If you could just mail me your idle/load temps or post it here :)

Your system was built with a high end CPU and a mid-range graphics card. Getting a second 5770 or replacing it with a more powerful 5870/5850 should give you a substantial FPS increase. No other upgrade is going to do much for you.

@cmcghee358

my core temps are idle 48.0 and full tilt 59.5, but I think thats mostly an airflow issue, I'm using an old case.


@ dndhatcher , Timop . rather than selling my 5770 and losing money, I'd rather buy another 5770. But it would really suck to end up getting stuck with two and having crossfire not work with a new game I like.

An your sure that this CPU won't bottle neck a 5870 or crossfire 5770's


@Timop I have the ram for video editing not gaming

Hmm, thanks for the info on temps. The 48C idle indicates the poor airflow of your case, but the top end is actually lower than mine in a 1200 Case with all optional fans. Makes me think I got a bad one maybe. (Im 40C Idle/61C Load)

Your rig actually looks built to handle gaming rather than video editing

From what I can tell/remember, the Intel i7 series is much better than AMD for video editing. Also, generally, video conversion/editing is more of a draw on the CPU, rather than the GPU. Actually displaying the video is where the GPU comes into play.

I just read the build is for gaming. Sounds like video editing is a side thing. If you are looking for better FPS on any game, upgrade your video Card. Your CPU is fine for the next 2 years+

It might also have something to do with nVidia and the Cuda etc that I dont know much about.

And no, 2x5770s or even a new 5850 wouldnt be bottle necked by the CPU.

AMD is awesome for efficient, quick and solid gaming/general use builds.

But Intel rules the mound when it comes to video editing/compression/conversion

Not a chance. Its AMD's current top of the line CPU.

The question is if your motherboard can do at least x8/x8 in crossfire or not.


I dont think there will be any issue with new games and crossfire. I dont know of any currently popular games where it is an issue. If you have some older game that you play all the time it would be worth checking their forums.

It's true you can easily push your 965 to 3.8 ghz, set it to 19.00x.
But keep in mind that'll raise your temps by about 5-6C so add in an extra side case fan and another one to the hsF if you can.

But I agree since oyu already own a 5770 another crossfired is your best bet.

"Something important, What is you PSU/mobo chipset?"

The PSU and the motherboard both support dual 16 GPU's

Hey,

I just want to thank you guys. I was really leaning toward upgrading my CPU and mobo. Now I think I'm going to go with the Crossfire 5770's.

It would have had hilarious results had you done the CPU/mobo route. You'd likely see the same kinds of speeds.

Definitely the graphics is the right choice.
