For people who have the money, buy two pcs, one F-57 just for gaming and the other is X2 or dual opteron workstation or desktop for all the work
If you can afford only one PC, then I prefer the X2, even if the F-57 will beat it in single threaded applications the X2 is still better...
Imagine this situation (we all do that even if we use the PC for mere gaming):
I run Doom 3 while I have Antivirus software and software firewall in the background. Also, I download a torrent file that eats 5-15% of processor power.
The single core processor running the game will be running at 80-90% efficiency dedicated for Doom 3 while the dual core will be 100% dedicated to the game as the other running operations will be handled by the other core...sweet isn't it?
Even if gaming will not benefit directly from the 2nd core, the X2 is the way to go for today and surely for tomorrow
