Need advice on older build - Looking for bottle necks.

I've spent a significant amount of time fiddling with and researching this rig. I think I've hit a wall and I am throwing myself at the mercy of the community :D

Before I shell out the money to build a new rig, I want to make sure I've exhausted this one first. This build is from mid 2008. (The newegg wish list is so old that I can't share it anymore, haha). I am not looking to max out any settings, I just want to squeeze a few more months of gaming from this pc. Note: the game I used for the load testing is still in beta. I have everything set to the lowest possible settings and my FPS is still horrible, especially if there is a lot going on. I think I've covered all of my bases here. Any help is greatly appreciated.

Note: A couple of months ago I upgraded the CPU cooler. Long story short, my new desk area is about 10 degrees hotter than some of my older places and it was causing some stability issues with the OC.

Any suggestions?
Should I worry that my MOBO doesn't do PCIe 2.0?
Am I missing something obvious in terms of bottlenecks?
Did I overlook a setting or two somewhere?


CPU:Intel Core 2 Duo E8400 Wolfdale 3.0GHz * (OC to 3.6)
CPU Cooler:Cooler Master Hyper 212 plus (i added a second 120mm fan)

  1. PCIe ver 1 will be a slight bottle neck with your PCI 2.0 card, but nothing you can do about that.
    O/Cing the processor may help a little:,1.html
    You could try O/Cing the 8800GTS:
    But I doubt you'll see much gaming improvement with the card. 1/2 GB with a dated card isn't really enough VRAM to play todays's games at high resoulution. Which begs the question; what rez is your monitor?
  2. Thanks for the response and the links!

    I've already pushed the CPU up to 3.6. The best I've been able to do (w/ stock cooling) was 3.75 but it wasn't very stable. I think the board FSB has overheating issues. I thought about bolting a small fan to the FSB heatsink but I think I'll only get marginal gains.

    My monitor runs at 1080p native but I have been playing games (where I could) in windowed mode at 1024x768.

    My last C2D was a 2.67GHZ E6700. (some years back) It was running at stock speed with a lowly 8800GTS 320MB originally. I was in a similar position as you. But after installing an HD 5770 1GB card, I was able to play any game of that time at 1680x1050 with all/most eye candy turned on. I only present this as an example of what simply upgrading the graphic card will do. Your faster E8400 should be good with a card in the HD 6870/GTX 560 range with very little bottleneck in most games. Even dropping down to the HD 6850/GTX 460 would do OK with 1920x1080.
  4. Good stuff. I'll probably go w/ upgrading gfx card and trying to push a little more out of my cpu w/ this new cooler. Thanks for the feedback!
