I understand the 560 is thought to be on average 25-30% faster, but what if I want to avoid spending more than 250? For our purposes, would the speed or the memory be of advantage. This question is for a single card solution for five-boxing with a good quad core and Ultra settings are nice but not necessary on the main. Medium settings the rest of the way with capped fps on the help.

Thanks in advance for any thoughts or input.
