General hardware guidance needed

[buggy]

That's good to hear. I'm going to call them on Monday to find out details.

That's a handy calculator -- thank you! I came up with a similar number, but depending on the cost differential I may limit myself to a 1000 Watt PS since it may be a while before I have all four cards. Either way, I'm not sure if BestBuy will let me customize the offering since it is a pre-configured deal. With the Dell I got from them I had to buy the bigger power supply separately, thus ending up with an extra one (they wouldn't do a swap and give me a rebate on the one taken out). So it may be the same way with this machine. At least it looks expandable. I'd prefer a hybrid hard drive to the one it comes with. Someone told me that that the O/S can be run in the solid state portion of the drive, saving RAM, but I should verify this.

I appreciate all the great advice!
