Upgrading from a GTX260 to a GTX570 will certainly bring a noticeable framerate improvement
while upgrading the CPU to a SB will not have much, if any, impact.
However, at your resolution of 1920x1080, a Q6600 @ 3.4GHz will likely act as a bottleneck for a GTX570 for some games.
To estimate the size of the bottleneck
-The first link below has a study that shows that an i7 needs to be roughly 3.6GHz to avoid bottlenecking GTX285 SLI at 1920x1200 for a variety of games.
-Assume a GTX570 (480 cuda cores) performs roughly the same as GTX285 SLI (240 cores x2)
-As clock for clock, Core 2 Quad lags a little behind an i7, I estimate a Q6600 needs to be, say, 3.8-4GHz to avoid being a BN.
Even with such a CPU bottleneck, I still think it is a better move to upgrade to a GTX570 as it can remain with you when you upgrade to the next platform.
(shows a QX9650 needs to be 4GHz to avoid being a bottleneck for GTX280 SLI at 2560x1600)
