I'm looking into upgrading my current set-up to run a triple monitor display. The cards will be paired with an i7 930 over-clocked to hopefully around 4Ghz. Currently the GTX 470 costs a small amount more than the 5870, but I wonder if that extra spent will hold a noticeable performance boost, if at all.
Thanks in advance,
It should be fast enough at that resolution to justify the performance difference,but don't expect extremely high framerates at demanding games with any choice.
