Alrighty A-Team. I spent some time this morning pouring over Newegg trying to find the best components to make an inexpensive build. I did my best to make sure that the system would be more than capable to run TF2 and be rock solid while remaining as cheap as possible. Here's what I've come up with:
Total Cost: $513.13
The cost is higher than the eBay system by $153.15. However, that cost difference gives you a much better system. In all honesty, I don't think you'd be very satisfied with the eBay system.
This build gives you a good graphics card. There are definitely better cards, but this gives you good gaming performance for $60. The other build didn't have a card at all; instead, it relied on built-in graphics on the motherboard. This would have severely hurt your gaming performance.
This build also gives you a dual core processor that runs at 2.5GHz. The other build has a single core that runs at 1.8GHz. That chip might work for today, but it will be a leash on your performance in not too long.
This build also has double the memory running at DDR2 800 speeds. The other build doesn't indicate what speed its RAM is.
I really have no idea what kind of power supply they have in the system you listed. It indicates a 480w power supply, but that could mean anything. As I've said before, the PC Power & Cooling power supplies are top-notch. $80+ probably seems like a lot when you consider that some power supplies are thrown in on the case, but $80 is a small price to pay to protect your components and provide rock-solid stability (no reboots and fewer blue screens of death).
This build has a 250GB SATA drive as opposed to a 80GB IDE drive. The SATA drives are capable of better performance. I don't think I have to tell you the value of having that extra space. You can save some money by getting a cheaper drive, but the 250GB is a great value. An 80GB Seagate drive will run you a little more than $49; that's nearly $.62 per GB. The 250GB runs about $70; for a cost of $.28 per GB. The 250GB is definitely the better value.
This build has a high-speed DVD burner. The other build only had a DVD reader. I looked up the price for the specific drive used in the other build, and it costs about $22. So, for $6 more, you get the ability to burn CDs and DVDs.
Note: Just like the eBay build, this system does not have an OS. As I've said before, that will run you at least another $80.
Tell me what you think.
