Well Munkey, it's a bit premature for you to be asking for suggestions when the purchase is so far away.(no offense) Especially now that we are on the cusp of new processors(AMD palomino), new memory(ddr Dram), and new chipsets (AMD 760 etc.). Anybody giving you a suggestion now would be doing you a disservice because things are bound to change very quickly in the next couple months. Prices change on a daily basis so any suggestions would be obsolete by the time you purchase parts.
My suggestion is keep coming to Tom's HS and find the latest news. Ask the same question about a week before your purchase than you will be making a more informed decision. As for prices go, check pricewatch- there more accurate than anybody on this forum.
