When you're shelling out a significant amount of cash for a gaming system, you'd like to think that you're getting the fastest system your money can buy. Sometimes that isn't always the case. So while the ABS Ultimate X6 ($3,199 as tested) contains the latest and greatest Pentium 4 Extreme Edition processor and certainly achieves a respectable level of performance, the system leaves us wanting more. Ultimately, the fault lies with the processor. While the P4 EE adds $450 to the system price (versus, say, a P4 660), it no longer delivers enough extra horsepower to justify the price premium.
