Odd framerates with radeon 6870

Hi all,

I recently bought a sapphire amd radeon 6870 and have been getting what seems like strange performance in games. For instance crysis plays on highest settings at 28-35 fps (1920 x 1080), but that only goes up to 40-60 fps on lowest settings with no AA, which to me seems weird. V sync is off. here is my setup:

Processor:
Core 2 Quad Q8400 @ 2.66 ghz

Motherboard:
Intel DP45SG Extreme Series

Power Supply:
600w (both 6 pin plugs are connected to the card)

Memory:
8gb 1333mhz DDR3

Graphics Card:
Radeon 6870

  1. See what happens if you overclock your CPU, lowering the settings makes the game more CPU bound.
  2. What brand power supply?

    What program are you using to monitor the GPU?
  3. Your CPU is slow and old. you're being CPU bound.
