Hi. I currently have a Bulldozer FX4100 processor (3600MHz), with 8GB of 1866MHz RAM (custom profile in bios), and a GTS250 (256bits, 1GB DDR3) video card. I'm planning on buying a GTX770 Phantom(256bits, 2GB, 7000MHz) video card. Will it bottleneck my processor or not?
I'm mainly using the rig for gaming. There was another thread about a Radeon 7950 that is close in specs to the 770 Phantom, and someone said that an overclock of the CPU will do the trick. I did manage to take the CPU up to 4000MHz without any problems but right now that is a bit of an issue. So,
- how can i find out whether a bottleneck occurs or not?
- how much to overclock the CPU (or how to find out how much to do it?); currently it is very hot in my country and i had to disable the turbo boost of the processor as it led to operating temperatures of over 70 degrees Celsius, which made my computer shut down all of a sudden. I just cleaned the fan and the radiator and it seems to have solved the issue, but i can't be sure in the long run (i'm testing things in similar conditions right now).
- is there some kind of unwritten law about CPU/GPU bandwidth or operating frequencies that can give me some idea about the occurrence of bottlenecks? (basically the 770 Phantom has ~20 times more bandwidth than the CPU and twice the frequency).
- i've read that the FX4100 is a fake quad core and that in fact it has only 2 active cores. Is there a way to unlock the other two? (i suppose this ensures the GPU will not bottleneck it; also in my bios it appears there are 4 active cores and not 2 - is this fake?).
Thank you
