I currently have:
2X GTX285 Cards running in SLI on a EVGA NForce 780i
8Gb Corsair Dominator Ram
Intel Q9550 Yorkfield Core Overclocked to 3.8Ghz (Liquid Cooled)
Coolermaster Comos case
1TB Samsung Sata2 Drive
2 X Western Digital Raptor Drives (150GB)
X-Fi Xtreme Gamer Sound card
27" Dell 2709W UltraSharp Widescreen LCD 1920x1200


Personally I am going to wait before I upgrade, SOW is going to be at least another year away and on past performance maybe 2. If you want to upgrade purely for SOW I would also wait to see what Oleg announces for the system spec's, we may be pleastantly surprised on how well SOW will run, given its time in development its fair to say that equipment used would not be currently 'state of the art'. If so by this time next year all current cards and CPU's will be a whole lot cheaper.
