New gaming build not up to par. Low graphics performance.

Hi all, I have just completed a new build and it just does not seem to be running as well as I think it should be. This is my second build I have done, my first build was done approximately 2 years ago and it went great and ran like I expected it to. I will list both my current and previous build specs so you know what I have to work with in case I need to compare parts.

CPU: AMD Phenom II x2 550 BE 3.1Ghz
RAM: OCZ AMD black edition DDR3-1600mhz 4x2gb
GPU: 2x Sapphire Radeon HD 5770 in Crossfire
HDD: WD Caviar green 500gb
PSU: Seasonic X-750
OS: Windows 7 Home 64bit

CPU: AMD FX-4100 3.6Ghz
Mobo: ASUS Crosshair V formula
RAM: OCZ AMD black edition DDR3-1600mhz 4x2gb(from old build)
GPU: XFX Radeon HD 6970 (Ver 1.2 without dual bios switch)
HDD(for storage): WD Caviar green 500gb(from old build)
SSD(for OS and games): 2x Samsung 830 64gb in RAID0
PSU: Seasonic X-750(from old build)
OS: Windows 7 Home 64bit

I built this new rig with the newer games in mind, as well as 3 screen eyefinity for games. As well as dipping into learning how to overclock once I had everything running right.

The Problem:
So far, the OS boots faster, but not quite what I had expected for the change I had made from HDD to SSD in RAID0. Overall Windows usage seems a little snappier. My main problem seems to show up in the graphics dept. Running Furmark 1.9.1 is worse than my dual 5770s I had previously. My dual 5770 ran 36 fps in 1080p benchmark, the 6970 runs at 30fps hitting about 70c. According to GPU-Z the gpu load hits 100% but the core clock only ramps up to about 580-600 mhz, not the 880mhz stock clock of the 6970. I decided to install Crysis to see how it performed with a high demand game. The core clock now ramps up to the 880mhz but the gpu load is at about 60%. With res at 1920x1080 and all settings on very high with vsync on it runs about 40-50 fps, not quite what I was expecting. I have yet to install Crysis 2 or BF3 as I want to get everything sorted out first. Both systems were running on the latest video driver from AMD 11.12. I tried rolling the 6970 back to 11.9 driver, but nothing changed. 3DMark11 ran 4365 on the old build, and about 4480(don't remember exact score) on the new build.

I am not sure if I overestimated my choice of components or not, but something just does not seem right. Any help will be greatly appreciated.

Thanks, Adam

  1. Just out of curiosity, did you install and use the driver disc that came with the new card? The reason I ask is some makers tweak the drivers for their specific card.

    You might also review the Tom's charts to see how it stacks up, if you have not already.,2659.html
  2. I just tried using the driver disc that came with the card and it made now change in performance. Not to mention it was version 10.11 driver.

    Thanks for the heads up on the comparison chart, apparently my card is performing like it is supposed to?
  3. I would rerun your benchmarks and see what you get now.
  4. I ran Furmark and it ran just the same so I went back to the 11.12 driver. I loaded up Crysis 2 just to see if a newer game with DX11 would change anything. It hit 880mhz core and the load was 100% as well so I guess it is running like it should. I just figured with a 6970 I would get higher than 30-40 fps with high-res and DX11 packs on a single 1920x1080. Without the high-res and DX11 packs it sits around 50 fps in Crysis 2. I OCed the card to 900mhz core and 1400mhz mem and gained about 3-4 fps. Battlefield 3 on ultra is running around 40 fps. 3 screen eyefinity isn't looking too promising with this card on its own.
  5. I was running eyefinity on my dual 5770s but it was too sluggish unless the game graphics settings were set to the lowest possible with 3 1920x1080 screens. Unfortunately the 6970 doesn't seem to be a whole lot more powerful than my dual 5770s I was running.
  6. I am not familiar with your GPU but we are running slightly similar builds. I have 4 gigs of 1600 mhz, an fx-4100 oc'd to 4.5 ghz (stable w/ a giant aftermarket fan) and a M4A Asus mobo. I noticed your psu is 750, just a though but it couldnt hurt to upgrade that a bit. I have a 1000 watt psu and I haven't noticed any issues so far. If your gpu has programs you can download to mess with its settings try that.
  7. A 750w psu is fine for what I have right now. If I add a second 6970 then I will need more juice. IIRC the 6970 calls for a 550w psu.
