ok I've seen many people post different definitions of what a "bottleneck" is
my general thought is that a bottleneck is the CPU not being able to provide enough information to the GPU in order to use the GPU to its full potential.
is this correct?
also If this is the case I think I can determine if a CPU will bottleneck a GPU by running a graphic intensive program, if the CPU reacheck 100% usage before the GPU then its a bottle neck, right?
all of that to say this, is there a way to determine what CPU will bottleneck a GPU without having them in hand, I'm wondering things like:
will an Athlon x64 x2 4800+ bottleneck a 5670?, what about a 4770? or 5770?
what if I slightly upgrade to an Athlon x2 4400e
or a Phenom II 555?
what if I unlock the Phenom II 555?
or to what Speeds would I need to OC in order to reach full usage of these GPUs?
what if I Xfire the 4770 what CPU would bottleneck it then, or to what would I need to OC which chip?
what about Xfire on the 5770?
basically I'm looking for a formula, or chart
does one exist?
I know these are mostly low end parts, I'm in the middle of building several low end machines for friends, and they're wanting to do some gaming with them.
but I would also like to see a chart or apply the same formula to higher end products.
