Gamers: Do You Need More Than An Athlon II X3?
By

We wanted to keep the comparisons crystal clear, so we're going to make it simple. We're pitting AMD's Athlon II X3 440 against a Core i7-920. Yes, the Core i7-920 costs more than three times as much as the Athlon II X3 440, but remember that game performance will be bottlenecked to a large extent by the graphics subsystem.

As far as graphics cards go, we test two configurations: one with a single Radeon HD 5850 and the other with two Radeon HD 5870s in CrossFire. We test the games across 1280x1024, 1680x1050, 1920x1080, and 2560x1600 resolutions.

Because the Core i7-920 utilizes triple-channel memory, we use three 1GB sticks for a total of 3GB of RAM. The dual-channel AMD platform will use two 2GB sticks for a total of 4GB. From our experience, the single gigabyte of RAM difference should have no effect on gaming performance, but if we see any disparity, we will make note of memory usage. The RAM timings and speed are identical between both systems.

We're using the Gigabyte MA790XT-UD4P motherboard with an Athlon II X3 440 and the ASRock X58 SuperComputer with Intel's Core i7-920. Note that the 790X chipset on the Athlon board can't support full 16x PCI Express (PCIe) bandwidth for each graphics card. To keep things comparable, we put the second Radeon HD 5870 in a PCIe slot with 8x bandwidth when using CrossFire on the ASRock X58 board.
