hey man you need to give us some more info. We need to know wha is your buget, your computing needs, and what builds your looking at. Just give us that stuff and anything else that is revelant. Also have you talked to either company about what you want?
I'm a gamer. I have other PCs for business. Budget? Hmm... I was thinking ~$2,000.00. I was going to buy a VM at my local BB. However, VM from BB is not available in Ohio. I didn't necessarily want to order online but I am now strongly considering it, in order to get better components.
Both are top-notch. Use the online configurators to get a rough idea of what you want then call each to fine tune your ideas. I have found that many things are possible that simply arnt in the web configurators. Components, OC, special touches, etc. Then compare and choose.
As has been said, do consider some of the other shops; OPC (overdrive PC), maingear, VM, AVA, ABS, puget to name a few.
Yeah, good point about the shipping. I am in Pittsburgh, PA and my shipping from AVA is only about $35 ground and $66 for 2 day, so yours should be next to nothing (or actually nothing, if you pick it up). That would definitely offset any taxes you would pay...
