The only reason to go to a new CPU for productivity gains is, IMHO, getting a 3930K. Personally I have a pure gaming machine so there's truly no reason to upgrade to a new CPU. My current mobo is being replaced because it won't run a 200 BCLK under Prime or IBT stress testing and even with OS on SSD the boot time is excessive compared to low-end Sandy Bridge systems like my HTPC.
Keep your 920 until a mainstream (<$350) chip completely blows it away.
Even in the situation that you need more cores (I eventually did when I started trying to record video while also doing heavily multithreaded tasks, etc), it's still a more elegant and cost effective solution to plop in a 970, 980x, or 990x, which you can pick up used for cheap right here in the OCN marketplace every time intel releases a new CPU and the ultra early "must have everything new for absolutely no reason" early adopters get new chips.
980x cost me ... I think $350? Sold the 920 for 150. As a side effect I was able to OC both the chip and the memory a lot higher too (I guess the extreme editions being essentially xeons means their IMCs are better suited to large banks of memory? *shruggity*). Total system upgrade for a end total of $200, a new high end mobo alone to support a 3930K would have cost that much. Besides... who doesn't want to say they own a $1200 CPU?
