I'd be careful about pricewatch, while they're handy for finding general postings of prices, some of the stores on there can be less than great about the overall experience for ordering stuff. If you're gonna use pricewatch as a guide, I must suggest you use
resellerratings in conjunction with it. If a store doesn't have at least a 7 for a lifetime rating, then you should be extremely cautious about buying from that retailer, no matter how good the price!
Just in case you were wondering,
newegg, tfp's computer parts store of choice, has a rating of 9.8 of 10 on resellerratings.
