first of all.... build a pc that will work for what you need today, plus a little more. Don't build a pc THINKING you might be able to squeeze a conroe into it, or AM2 for that matter. By the time you NEED to upgrade, you would be better off buying a new motherboard anyway. That said, you also should take into consideration the amount the motherboard is going to cost. Since you do not plan on overclocking, you could probably get away easy with a sub $100 mobo from either side. I know for a fact you can with an AMD system. A $75 dollar mobo would do just fine. Asus A8N5X is actually pretty good, and stable. On the Intel side, a little lower performance than the X2 3800... probably not noticable unless you bench it. Other than that, I am not quite sure of the stability and quality of the $75 motherboards which you could buy for a 930. I imagine it is about the same quality..... maybe better.... but to be honest I don't know.... have only looked into putting one together.... never did though. Back on track.... the 930 with a $75 intel chipset mobo would be the least expensive route.... but if you buy the more expensive mobo, it would make the price difference up between the two cpu's which is only about $75. And keep in mind, at stock frequency the X2 3800 is faster than the Pentium D 930, uses less power and runs a little bit cooler..... if that $75 dollars is of concern.... then the choice is quite obvious.... Intel P D 930 with an Asus motherboard Intel chipset that will fill your needs for that price range.... as long as you do not want to OC(inexpensive mobo).... but that pentium D will OC quite a bit.... might even be faster at max oc than the X2 3800 at it's max OC which is usually around 2.6Ghz, from my experience. But, that I cannot be sure of.... it may actually be slower.... 4.5 to 2.6... haven't found the comparison yet. Sorry, got a little off topic...
