I am planning on building my first gaming PC sometime soon, and having wandered these many internets, I have come up with these specs. Apparently, these should play Crysis on highest settings, or at least with everything but AA turned up.
However, after reading about how much spiffier it'll make Mafia II, as well as some other things, I'm really interested in PhysX. It's my understanding that I can only run it on a nVIDIA card, so here's my question. Would my best best be buying a GTX 480 (http://www.ebuyer.com/product/202284) for £100 more, or two GTX 470s (http://www.ebuyer.com/product/202279) for £300 more, bearing in mind that if I went the 470 route, I'd probably buy one now, and a second in the future?
Also, I'm pretty sure it is, but is that every component I'd need, and will they all work together?
