Gfx card comparisons are irrelevant now, I think. The huge leaps between card revisions we used to get years ago (5800 Ultra Hoover, anyone?) just aren't there anymore, and even cards costing £150 can run Crysis et al at fantastic settings at 1080p. Perhaps this is because of the shift towards developers programming for consoles and then PC ports just getting a few extra whizzy settings that in practice do nothing other than give e-peen boasting prowess of 60fps @max settings, I don't know, but certainly paying £1000 for a dual SLI setup doesn't give the gains of previous years.
I left PC gaming years ago because the more rounded experiences were to be found on the consoles for the games I enjoy, and there's nothing there now or in the future that could tempt me back. What we need from the next gen consoles isn't super whizzy graphics, although that's always nice, it's different experiences. I doubt we'll get it for the first couple of years, but make no mistake this is a critical time for gaming and the manufacturer that leads the march towards 5-min social or cloud-based experiences will be very successful.
Which is a shame.
