I don't plan to run many programs at once, it's just a recreational computer I'd browse and download with, nothing heavy. I mess around in photoshop/sony acid/after effects but nothing intensive. Just mainly playing games, really.
Hell... a E2xxx could do all that for ya, and then some. An E4500 could do a lil more, and going to E4600 I really don't see the 200mhz worth it for stock speeds. I haven't seen any E4800. (edit - unless you are talking about the E8400 :lol
The main question is... do you want to save the most amount of money, get the best bang out of your buck, and how much your willing to spend, but trying to keep in mind to have a decent upgrade path to follow.
Gaming will be depending MORE on the GPU rather then the CPU, unless it has been optimized for more then 2 cores.
So even if you do get the best processor out there, you may be disappointed if you slacked on a good GPU.
