I have been moling this over and searching all over for an answer but I can't find exactly what I'm looking for. I am trying to figure out if my sub par ratings in heaven(~750) and 3Dmark (13240) are a result of my power supply of a cpu bottleneck. I am running an Nvidia GTX 470 with an Intel Q6600 G0 processor clocked at 2.80 Ghz and my PSU is a 600 watt with I think to be two 18 amp rails for my GPU. I am getting the same results as an SLI setup of 2 GTS 250s which I think really isn't right at all. I thought the GTX 470 would greatly improve game performance. Any input would be appreciated.
I was expecting to run all games that I had been playing much better than they were before with the 2 other cards, at least thats what I was lead to believe anyway. That is besides the point though. I just want to know if my processor is causing a bottleneck or if my PSU is causing my card to under perform.
CPU BOTTLENECK(I'm sure). You will get a HUGE performance jump by a better processor. A GTX470 definitely deserves an i5 750(minimum) and you will need i5 750@ 3.8 to 4GHz to unleash max performance.
Trust me. I saw a benchmark for GTX460 where Frame Rate literally doubled in each benchmark for E8400@3.6GHz vs a core i7.
