If you are no longer content with using just two high-performance graphics cards in your computer, then performance PC maker Voodoo PC now offers an opportunity to sink your savings in. The new "Omen" PC can be equipped with virtually any high-performance PC component money can buy today.

The device comes either with a single-core Athlon 64 FX-57 or a dual-core Athlon 64 FX-60 CPU (or regular Athlon 64 X2 processors), a liquid cooling system, up to 4 GB of memory, a maximum of 2 TB of hard disk space and optional premium audio enhancements. Prepare to pay about $7500 for an entry-level quad-SLI system and more than $10,500, if you go for the high-end version. A monitor is not included in the price.

Hard-core gamers have used regular SLI for more than a year. By combining the power from two separate graphics cards, frame-rates can be boosted by as much as 70%. Quad SLI takes that one step further by using two Nvidia GeForce 7900 GTX cards with two graphics processors each. Voodoo says that this will let gamers run at 2560x1600 resolutions with 32x antialiasing.

Several other vendors have also announced quad SLI systems recently, most notably Dell and Alienware.
