Well I have made the jump to dual core, and my first personal mobo that can overclock; ordered today so hopefully either by tomorrow or Friday i will have my parts. I was originally going to get a new vidcard also but with Vista and DX10 around the corner i just figured better to wait as my x800 gto@16p is still chugging along and it just didn't seem right replacing it so soon (only had it for about a year). Newegg has the x1900 AIW for 299 which considering that its only difference from the regualar x1900 xt is clocks was a hard choice to make. Here's what i got: 1 XCLIO XClio 450BL ATX 450W Power Supply - Retail Item #: N82E16817189003 $43.99 1 AMD Opteron 165 Denmark 1000MHz HT Socket 939 Dual Core Processor Model OSA165CDBOX - Retail Item #: N82E16819103588 $327.00 1 DFI RS482 INFINITY Socket 939 ATI Radeon XPRESS 200 Micro ATX AMD Motherboard - Retail Item #: N82E16813136007 $87.99 1 G.SKILL 1GB (2 x 512MB) 184-Pin DDR SDRAM DDR 400 (PC 3200) Unbuffered Dual Channel Kit System Memory Model F1-3200PHU2-1GBNT - Retail Item #: N82E16820231030 $80.99 Subtotal: $544.96 Tax: $39.51 Shipping: $20.14 Printer-friendly Version Total: $604.61 My wife was freaking till I explained that i have all the parts to build another PC but she would rather I get that 400 dollar Walmart Sempron special and she doesn't understand that with the 165 Opty even if I can get even close to 2.6ghz I will have saved a bunch of money and made a much better system for the long run which is more future proof thanks to the Dual core. My current rig sans vidcard is going to my kids room. Last order I made in the evening and got it the next day as I live in socal. I figured that although my current PSU might not be suited to overclocking and the Xclio seemed good for the price and has decent reviews. This Pc will eventually be an HTPC so crossfire is out. Let me know what you think about my choices good or bad. I was stuck with mATX for now so my options for OC boards was really limited. I am an ATI fanboy as they have been good to me over the years and I still have a bitter feel for nvidia over the whole Voodoo fiasco (original SLI). Nothing wrong with Nvidia have helped build systems for others with their hardware its just my personal choice. I will post the stepping once in hand.
