The rear of the Studio XPS offers several more options. In addition to four more USB2.0 ports (bringing the total to eight), there is another FireWire, one eSATA, gigabit ethernet, audio in as well as analog and optical audio out. One thing you can see in the picture is that the Studio XPS has no onboard video whatsoever; this is because it's only configurable with discrete graphics cards. In this case, it's an ATI Radeon HD4850, offering up two DVI-I video out ports as well as s-video. It's certainly an interesting move by Dell. The back of the computer also offers up a cable lock slot.
Inside of the computer, there are external 5.25" and 3.5" drive bays available (one of each) as well as two more internal 3.5" drive bays. There are three PCI-e x1 slots and a single PCI-e x16 slot which is already taken up by the discrete graphics solution.
Benchmarks and Performance
wPrime is a PC performance benchmarking program that forces the computer to perform recursive mathematical calculations. This program is multithreaded, meaning we can take advantage of more than one core of a processor at a time, resulting in a more realistic estimate of a computer's performance.

It's interesting to see that the Studio XPS, with its new Core i7 processor, beats out the $3500 Area-51 desktop. It falls behind in the 3D tests, however, which is no surprise considering the disparity between the graphics cards. It's easier to see where the scores differ in 3DMark Vantage: the Alienware machine had a combined score of p12578 while the Studio XPS scored p7603. It gets more interesting when you look at the subscores. The Alienware had a GPU subscore of 13148 and CPU subscore of 11129. The Studio XPS, however, had a GPU subscore of 6407 and a whopping CPU subscore of 17275. It won out in PCMark Vantage, which relies much more on CPU performance than its 3D counterpart; the Studio XPS scored 6056 while the Area-51 pulled off 5976.
Audio and Video Compression
The Core i7 920 within the Studio XPS is what makes the new desktop so attractive: it crunches numbers astonishingly fast. In our tests, the computer was able to compress 602MB of WAV audio in 21 files to 320kbps MP3 in just 36 seconds -- which is more than twice as fast as some of the flagship parts from AMD.
We also ran a short video compression test in which 21 minutes and 42 seconds of MPEG-2 video footage was run through a one-pass x264 encoder. Taking just 10 minutes and 41 seconds, you can start to see the potential for professional who work with media day in and day out. Given that even these programs weren't completely capable of using the 8 threads offered up by this new quad-core processor, as developers come up with updated codecs and programs, we can expect to see performance improve dramatically
Gaming
Despite Dell's claims that the Studio XPS is not considered a gaming desktop, we couldn't resist loading up Crysis and seeing how well it could run. Even though the game is much more GPU dependant than CPU, performance was still admirable. Running at 1280x1024, 0xAA with all settings maxed, we saw an average of 21.164 frames per second, with a min of 18 and a max of 25. Mostly playable, but not all the great. Keeping the same resolution and anti-aliasing, but reducing the settings to "just" high instead of very high, average frames per second shot up to 33.768, with a minimum of 29 fps and a max of 41. While a dedicated gaming system would certainly get better scores, you could still pull off a few rounds of the latest game in between compressing video.
