You really want a GeForce GTX560Ti
instead of that GeForce GTX560. Don't let the evil marketing geniuses' intentionally-confusing product naming claim another victim. This hot-clocked Zotac AMP! ZT-50302-10M
looks like a good performer for $230 -30MIR. You might get even better bang for your buck with a Radeon HD6950
for the same price.
I agree that your motherboard choice is fine and that you should wait for the -K processor.
