It looks like Dell is intent on keeping up its in-house rivalry with Alienware, upping it's top-of-the-line XPS 700 gaming PC to include overclocked Intel Core 2 Extreme CPUs -- but still no AMD processors, overclocked or otherwise. The desktop is also getting a significant upgrade on the graphics side of things, with the highest-end option now hitting up two Nvidia GeForce 7900 GTX cards operating in SLI mode, replacing the earlier single GeForce 7900 GS card. Availability appears to be dependent on Intel actually delivering the goods, but Michael Dell himself says that the system will be available the second Intel announces that it's good and ready. Exact pricing hasn't been announced, but we're guessing it should come in somewhere below $10,000. Just how far below 10k is yet to be seen.
