New PC? Buy basic and build out as needed
Gizmodo's Prof. Dealzmodo takes a similar approach to buy PCs as I do. Buy a low-end machine and then buy third-party components if/when required. You can read the Gizmodo article to get an idea, but I'll also throw in some of my own thoughts. First, you must get at least 2 GB of RAM. If you can still get Windows XP, then you can stop at 2 GBs. If you are stuck with Vista, add at least 1 more GB -- if you add 2, giving you 4 total, 0.5 GB will go to waste unless you go with a 64-bit Vista.
