you are right, Mister, i apologize. here is the right run at 4GHz Quad on my Phenom and the 7970 at stock . . .
Pretty good numbers for a Thuban.
To be fair, that benchmark makes it look like the Shogun 2: Total War play experience is going to be significantly worse with any processor other than an Ivy Bridge. As a matter of actual practice the real-world difference only shows up in the largest of large battles (absolute max unit numbers & sizes for single-player or 2v2 multiplayer battles or something like that), and other than those scenarios, which the CPU test basically replicates, a CPU like your Thuban is going to perform swimmingly (like in the GPU test you ran). It's only in those relatively extreme situations that the improved performance of ivy bridge is going to be a noticeable improvement.
As with any modern CPU vs CPU discussion, the real-life benefits are typically on the margins and not on the level of "playable or not".
