I may install Crysis demo tommorow on my brothers PC, which is basically the same except he has an 8800GTX, and I have an 8800GTS 640, to see if running using the Very High settings hack, wheather its more playable on that.
If so, I may be tempted to sell my 8800GTS since I still have the box and that, and buy the 8800 GT since even though it has less ram, its now overall, the better card, and should run Crysis well, with around 25fps if I'm not mistaken from benchmarks.
Heck, maybe I'll be okay anyway, and the retail version MAY just push the Quad that little bit more, pushing me just over 20fps on High (Very high mod) and I may be happier.
I don't mind running in Window mode (I just hope in the retail they have other widescreen settings) as I don't get stretching and can run it at a native res, albeit, acting like a smaller monitor, but ah well.
@MattieDaShark83, Yeah, I didn't think it's that bad either, and at that setting, it's my full monitors length downwards, but with borders either side, which I don't mind if I can play it as its meant to be.
I wasn't prepared to drop the quality though, not for a new computer like mine. It was either going to run at full, or not at all
The retail version I've heard has more tweaks than the demo anyway (i.e, seperate settings), as the demo doesn't give you much in the way of settings for different parts of each sector as it were.
