In this installment of the System Builder Marathon (SBM) series, our mid-priced PC is more than just a solid machine built from great components. Instead, it's also an experiment to see exactly what benefits Intel's Core i7-920 offers when compared to the cheaper Core i5-750.
We used the Core i5-750 in our last SBM, and this is an excellent opportunity to show the difference between the two. With the price of some Core i7-capable X58-based motherboards dropping, the real-world difference in price between a home computer based on either of these CPUs is probably in the $150 range. Since we'll use the same type of Radeon HD 5850 graphics cards in CrossFire that we did in our previous SBM, this new build gives us a really good idea of what the extra cash invested in the X58 platform and Core i7-920 provides in the way of performance.
Here are the components we chose:

We call this the $1,500 build because that's what we paid when we ordered it, but prices have changed quickly in the past couple of months. The PowerColor Radeon HD 5850 graphics cards we selected have increased in price to $320 each, but only a short while ago these cards could be had for $290. This accounts for the lion's share of the price increase and is an unfortunate side effect of what happens when a company has a virtual monopoly in the high-end graphics card space. If Nvidia provides some competition with its next-gen parts in the near future, we might see some healthy competition on the price front, which can only be a good thing for the consumer.
Regardless, the point is that even though the new system's price is almost $250 higher than the Core i5 system we tested in November, the price of building that same Core i5 system today would be much closer. Is the Core i7-920 CPU worth the price spread when compared to the i5-750? That's what we'll try to answer with this comparison. Now, let's examine our specific component selections.
