AnandTech checks how well the ATI Radeon HD 5870 scales on the Intel P55 and X58 platforms, you can check it out over here. The conclusion is that X58/Bloomfield is the way to go the pump the maximum amount of performance out of a multi-GPU setup, while Lynnfield will give you a more cost-effective platform with lower power consumption and less heat output.
In the meantime, we have our first performance results comparing the Core i7/860 and P55 against the like priced Core i7/920 and X58 in a variety of games. We are going to state this upfront, this is not a GPU review of the HD 5870. Instead, we decided to pull this information out of the upcoming high-end P55 roundup so it did not get lost in the mix. Our resolution is limited to 1920x1080 that we use in the motherboard test suite. As such, the numbers speak for themselves. So let’s get right to the results today, but first, the test setup.
