Why buy a computer when you can make a better one for less?

 As I write this, my completely-full 160GB IDE hard drive is making a very unhealthy sound, and I'm trying to make sure I don't get too many browser windows open lest my single-core processor gets bogged down.  Yep, it is time for a new desktop.  This one has served very well over the last 4+ years, but its time to go to Dell.com and . . . what, what?  

I built this computer with my own hands . . . I'm already on my second power supply and I put in an updated graphics card a few months ago.  There is a lot of good stuff in there, and the case is still rather sexy (in my opinion). I figure I can Frankenstein my current system to compete with a much more expensive high-end gaming system.  So, I logged onto Tom's Hardware and did some research, then I went to NewEgg and ordered a bunch of stuff.  I'll be comparing my build to a basic Dell Studio XPS 9000, as that is the closest decent rig I could find to the price that my build is coming out to, and because in my experience Dells have been good, reliable, and well-built machines.  Below is the list of items in my shopping cart:

Sony Optiarc DVD/CD Rewritable Drive Black SATA Model AD-7240S-0B

Sony Optiarc DVD/CD Rewritable Drive Black SATA Model AD-7240S-0B

Sony and NEC have combined their optical expertise in the joint venture, Optiarc. The result is the Optiarc DVD and CD drive series. With write speeds as high as 24X for DVD+R and DVD-R, they may be the fastest SATA optical drives in the industry. Even at these speeds, there's no need to worry about buffer under-runs, with 2MB of memory buffering your data. Optiarc's technology adjusts itself automatically to the small variations in each drive and each disc as it writes, giving optimum performance time after time. All the features you've come to expect in a modern DVD/CD burner: multiple media formats, inexpensive price, fast operation, and now backed by both Sony and NEC. It's always your decision, but I wish I had a dead drive right now so I could replace it with one of these. Type: DVD Burner Cache: 2MB DVD+R: 24X DVD+RW: 8X DVD-R: 24X DVD-RW: 6X CD-R: 48X CD-RW: 32X


AMD Phenom II X4 955 Black Edition 3.2GHz Socket AM3 125W Quad-Core Processor

AMD Phenom II X4 955 Black Edition 3.2GHz Socket AM3 125W Quad-Core Processor

Like the superheroes of old, the AMD Phenom II X4 955 streaks out of the night to lay waste to your enemies with four 3.2GHz cores that have dedicated L1 and L2 caches for each , and 6MB of shared L3 cache to handle really heavy loads or large data sets. Memory transfers get faster than ever. HyperTransport Generation 3.0 mode allows up to 16.0GB/s of bandwidth. Up to 17.1GB/s memory bandwidth for DDR2 and up to 21GB/s memory bandwidth for DDR3 memory controller delivers an amazing total of 37GB/s of processor-to-system bandwidth. This unprecedented bandwidth is needed to feed the data hungry AMD64 with Direct Connect Architecture cores. You'd think that all of this power would be too hot to handle. Think again. AMD's Cool'n'Quiet 3.0 works with CoolCore Technology to minimize heat while keeping power and efficiency up. Now the cores can shut down unused parts of the processor when not in use. This saves power and helps to reduce the amount of heat generated. This function is built in so there's no need for drivers or BIOS updates.

The whole order, including tax, shipping, and several rebates and specials which might not be the same at the time you read this, ended up being $669.81. Granted, I'm using a graphics card I already bought a couple of months ago, so for a fair comparison I'll add that in.  It is a BFG GeForce GTXS 250 with 1GB of RAM and a 750MHz core. It cost me around $175 I think, but now its unavailable on NewEgg and you can probably get something even more fancy for that price or less today.  To be fair, I'll put the price of my system at $800 being that you can get the same graphics card or equivalent for about $130 or $140. That is pretty close to the Dell at $899. Granted, that is not including a powersupply, case, and cooling, but I'll keep the comparison at that since most people who are upgrading already have those things in their current PC. If you need those, however, you could get everything for about $150-$200 if you want something that is nicely built and sturdy.

Now let's compare what my rig will be against our base Dell Studio XPS 9000. Advantages are in bold.

 So in conclusion, by buying my own parts, I think I'm getting a lot more PC for the buck than buying a pre-made one. Even though Tom's Hardware recently favored the Core i7-90 to the Phenom X4 955, the fact that the motherboard on my rig has a front side bus that is over twice as fast, my rig will let the processor live up to its true potential, where the processor on the Dell will be somewhat limited. Even if you needed the case and power supply, the machine will give the next level XPS 9000 a hard run for its money. The upside of the Dell, however, is that Dell spent a considerable R&D effort in getting components that work well with each other, and that the Dell will be covered by professional tech support.  But come on--if you have read this far, you're probably not worried about calling tech support ;)

I will write another post once my parts come in and I put them in my case/fire up the system (assuming it fires up). I'd like to benchmark it against a base XPS 9000.  Anyone got one?
