Alien to be honest do you need a new system ?
It won't matter if you wait for SoW as hardware is changing so fast it will be out of date in under 6 months anyway.
The problem is you need to step on the ladder its just a matter of when and how much depreciation is involved, sometimes its best to buy around the 6 month old barrier to get the best deals, as new hardware is released the older stuffs way cheaper and possibly more stable as its had longer in the retail end of the market.
So you can blow 1000's or 100's, most of my punters want the "must have" stuff just because someone's posted a benchmark saying "my roof flew off it was soo fast in Crysis" etc etc etc
Personally I can build a system around the 6 month old area that will perform as fast as the latest must have syetems, its a matter of careful hardware selection and price, but the cheapest isnt always the best go for a recognized GPU manufacturer, some of the cheaper ones are cheap for a good reason.
