Re: What is the bottleneck?
ah, indeed you did. a bottleneck si when one piece of hardware bogs down another... for example if you have an old pentium processor and a current gen graphics card, the processor would severely limit the performance of the graphics card. that is a bottleneck...
what i would suggest doing is buying a 6970 or a 570 and sell your 5770s for $100 each to make up the cost... also get a CPU cooler ( if you dont already have one ) and overclock your processor, 3.8 to 4.0ghz is very tangible with that chip and you would have a very capable little rig!
with your powersupply i wouldnt suggest anything higher than a 6970 or a 570, any cards high than that might string out what your power supply can do a little too tight...
