I know I have posted a couple of topics recently regarding upgrading my system. However these are now slightly irrelevant as I have come into a bit of money (by chance) and will be looking to upgrade my monitor to a 30". I've been looking at the Samsung SM305T and the Dell 3008WFP. I've looked through a lot of benchmarks of various GPU configurations (Since my mobo supports SLI, I will be wanting an Nvidia card). The most suitable options for this would appear to be either a pair of 570's in SLI or a single 580. I've heard good things about the scaling on the 500 series cards so my concerns about a multi GPU solution are reduced somewhat. I suppose another thing to consider is my CPU bottlenecking this kind of graphics power. I'd just like to hear some opinions from those that are wiser than me, if it's not too much trouble. Cheers.
