Hmm, lemme think on this, then. OK. Sub-$500 budget, needs to run E:TW...
Guys, this does look like a sweet processor to build around! I like how BZBoyz makes suggestions for compatible motherboards and such when picking a processor!
As I've mentioned, I'm in pursuit of a new PC build *in reality* and I wouldn't limit myself to $500.
Being a non-gamer, I would not need a dual video card setup to start. Even onboard discrete video in a motherboard might work for the time being; I've seen some motherboards advertised with that feature.
However, in the timeframe before my next major rebuild - typically three to four years - I might want to run a high resolution flight sim or something. So the motherboard I choose now should be upgradeable to SLI/Crossfire.
