Well, it's good to see that you've been keeping my thread alive while I've been away. Cool to see some benchmarks from people running similar systems too.
Also, as some of you have posted, my system is bound to be heavily CPU limited in heavily CPU limited titles. That's a given, and not really up for discussion. It's a no-brainer that my PC will be handily beaten by newer systems in heavily CPU-limited games like Civ. What I'm looking for is exploring what kind of performance gain this crazy upgrade would get me here and now, in the kind of games I play (and for the record, I only play Civilization as a board game

).
Alas, there is some bad news. Again. I do feel like that's all I've been posting here ever since I first started the thread. As you know, my PSU died. So I bought a new EVGA Supernova G2 750W. Overkill for a build that will never see CrossFire, but it was the most reasonable way to get a great PSU with a 10-year warranty. Alas, I'm already having to use that warranty. Something inside the PSU has blown itself utterly to pieces (anyone have any idea what this is?

In the meantime, I'll pull the SSD from the computer tomorrow and post what I have. I managed to run the Shadow of Mordor benchmark (2560 Ultra) before the PSU went kablooey, and essentially matched the numbers from Tom's Hardware's review of the Fury X - slightly lower minimums (a few FPS), but virtually identical averages. And, of course, a HUGE gain from my old GPU.
