The newer cpu's are indeed better and similarly priced, but you've then got to buy a new mobo and new RAM, for only a little extra perf. for a cheap upgrade, just the cpu is best right now, beyond that a new platform is needed.
I guess if that's the way you gotta upgrade, then that's what you do... I just really like some of the more expensive options out there - i3-2100 is one example. Just feels like you're putting a band-aid over the wound.... and eventually you'll want everything else that goes with the newer motherboards.
like what? i'm in a similar position, other than quicksync, what exactly am I missing. P5B D/L & Q9550 & 6GB of RAM. I could spend £300-350 and bench slightly higher, game very slightly faster (when CPU limited, which I'm generally not). But otherwise have no discernable benefit? And UEFI? not really a benefit.
