Sure, Alienwares are incredibly overpriced, but it's not as simple as going to Pricewatch and buying the cheapest part. Never, ever buy parts from companies listed on Pricewatch unless you check their rating on

I honestly wouldn't buy anything from a company that has a rating less than 8 out of 10. There's a reason NewEgg has an incredible rating (9.8 out of 10): their RMA service. If they ship you a defective item, it gets sent back ASAP and you get your damn money back. It's as simple as that. There are other companies out there (lots of them) that do NOT offer refunds after you spent $500 on a new video card. There are tons of companies out there that offer 30-day return policies in which they mean it takes 30 days to get a refund. There are companies out there that will send you a MDI hard drive after you ordered a Western Digital Caviar, then have the MDI fail after a week. Never, ever buy anything from a company that is not rated well. It's not worth saving money if the pieces don't work and you have no way of returning them.
I've ordered about $2,000 worth of computer parts from NewEgg in the past year. Guess what? I've RMA'ed every single piece of it back. Yes, I've sent it all back, simply because there were problems with the hardware. Hell, I ordered TWO GeForce FX 5900 Ultras for $500 each, and BOTH of them came broke. This is what makes a company stand out on the Internet: Both cards came to my house in 3 days with standard shipping, both were broke, both were RMA'ed, and a week later I had my money back. There aren't many companies out there that will do that for you, but NewEgg does. They strive for excellence in one major field: return services. Find a company with great return services and you're set.
I'll still order from NewEgg simply because of their great RMA service. Hell, even considering I've returned $2,000 of merchandise to them. That's where it counts, though: I was able to return it quickly and without hassle.
