That's ironic, because I could never get my AXP 2600+ Barton/nForce2 rig to outperform even an AXP 1600+ Palomino/SiS735 rig in real-world apps.
For starters, although my nForce2 mobo had five PCI slots, three of those actually share the same IRQs as devices in my system (the SATA controller, because my main Windows drive is an SATA drive, and my AGP videocard) that don't like IRQ sharing at all whatsoever. (This IRQ sharing is locked in hardware, and cannot be changed at all through the BIOS. And any attempt to change an IRQ for one of those given slots will also change the IRQ of any devices that also share the same IRQ as the same slot to the very same IRQ as the slot being changed.) And the two PCI slots that don't share IRQs are both located too close to the AGP slot and the CPU for comfort.
Second, I've read that nForce2-based motherboards don't like tRAS being set to a value other than 11, especially when overclocking. But my memory is rated at 2-3-2-6 (the last value being the tRAS setting) - and my NF2 mobo's BIOS would set it to either that or to 2-3-2-5. Normally, lower numbers should be faster - but that timing mismatch between the chipset and memory can cause sluggish performance and unexpected instability.
Which comes to the third point: Because of the mismatched timings, my gaming framerates paused long enough to seriously affect playability. And Windows 2000 and XP often crashed to a BSOD.
