get an am3+ motherboard and wait for piledriver, my 1055t at stock plays bf3 no prob with a 6770, lower end card but i play high settings @1080p with 30+ fps and cpu isnt near %100. I know Skyrim isnt going to use 6 cores, but OC it with a new board and if it still hurts turn off 2 cores and upgrade to a piledriver fx cpu, those will prob and hopefully will be better than bulldozer and older Phenom II x4/x6.
I've had my cpu to 3.4Ghz, and i dont notice any difference but my gpu isnt being bottlenecked by the cpu so i guess i dont see anything, i dont keep it oc'd cause my fire starting msi mobo, and low end psu, but there getting replaced and will enjoy my 6 core with hope of not upgrading for a while.

PileDriver will probably be only a 10% improvement over Phenom II / FX which will make it as fast as a 1st generation Core i3/i5/i7 CPU. At this point we can only wait for the CPU to be released and benchmarked, but I believe a 10% improvement is a fair assessment.
If you believe you CPU is holding back your performance, then you want an 3rd gen Ivy Bridge Core i5 CPU. Naturally it will likely cost more than a PileDriver CPU, then again if PileDriver can indeed match the 1st gen Core i3/i5/i7 CPUs, then Ivy Bridge CPUs will be about 18% faster than PileDriver. I'm sure the price difference will likely be a little more than 18% between a PileDriver CPU and it's comparable Ivy Bridge competitor, but going for a more powerful CPU means that in future you are more likely to upgrade later rather than sooner, thus saving you some money in the long run since you are more likely to postpone upgrading.
