Having recently bought Bioshock 2, it's now become painfully obvious that a GPU released in 2007 may not be the most appropriate choice (nVidia 8600GT). I'm running XP with a i7-860, p55 mobo and a 750W PSU, with a 1920x1080 monitor. I would like to crank up the AA and AF as far as I can, but recently I've made concessions in order to actually get my games to run.
I'm looking at buying a Radeon 5850 ($399 AU), which I'm sure is still in very short supply, or a 5770 ($198 AU). I really hoped that Fermi might have been a more tangible option, but it just isn't, so I'm swallowing my green pride and making the smart decision.
From what I can tell, the 5850 is twice the price of the 5770, for roughly 1.5 times the hardware specs, and about the same in terms of performance. I've never run a dual setup before, so I was wondering whether buying 2 5770's and adding a $30 Crossfire bridge would be any good. I've read plenty of forum posts that say just getting a single 5850 is the better option because it has the option of expanding in future, rather than filling both PCI-e slots with lesser cards now.
My main question is, given all these modded drivers out at the moment, will my old old (old ) 8600GT be of any use as a dedicated PhysX for games like Batman: AA? Any thoughts on the ATI cards will also be appreciated.
