I thought we convinced you to get the 6950 2GB in the other thread because you were considering CF in the future. Either way best value for a 560 right now is this Gigabyte 560 for $215
after rebate and free shipping. It is definitely the card to get over the EVGA or MSI, it;s cooler is very similar to the TFII on the MSI as both have 4 heatpipes and no VRM heatsinks, It has a higher factory overclock, and is $20 cheaper to boot, easy decision in my book.
That is the best 560 to get right now and would probably match the value of the 6950 if you're just considering single cards but if you are considering CF or SLI still then definitely go for the 6950 2GB
they scale ever so slightly better than the 560 but he biggest factor is the 2GB will let you do things that you just can't with 1GB
