In regards to what?im currently building a new pc. is this too much ?
How much RAM are you using, and what is the power supply?
A 600w unit is overkill for your intended system, but I would be more concerned if it was a budget model as they should be avoided.
You shouldn't run into any compatibility problems. from what I know.. Some AMD boards do not support SLI set ups. But I believe yours support SLI and CFX.. So you shouldn't have any problems running a GTX560 because your only running a single card anyway.by choosing gtx 560, wouldn't it be incompatible to some feature on AMD motherboard ?
