Hi guys, I have bought an extra GTX 760 for my rig and noticed that it is actually slower than my actual single GPU. Tested in 3D Mark and a little play off in Crysis 3. So, here's my rig: MB: Gigabyte 990FXA-UD3 PSU: Sirtec High Power BR12 750W Bronze CPU: AMD Phenom II X2 550 BE , stock clocks @ 3,1Ghz (which, by the way, cannot be unlocked) RAM: 8GB DDR3 Corsair @ 1333 Mhz Dual channel / 2x2GB + 2x2GB GPU 1: MSI GTX 760 Hawk / 2GB GPU 2: MSI GTX 760 TF Gaming / 2GB Onto the benchmarks: Icestorm / Single GPU / GTX 760 Hawk : 62394 Icestorm / SLI GTX 760 : 55617 Firestrike / Single GPU / GTX 760 Hawk: 4248 Firestrike / SLI GTX 760: 3726 Tried even an OC to the CPU: Stable OC was @3,5Ghz: Icestorm / SLI GTX 760 : 67002 Firestrike / SLI GTX 760: 5513 Any ideas why these little numbers? Maybe the CPU bottlenecking? If this is the case which AM3+ CPU should I get? Is the AMD FX 6350 enough? Thank you for your help !
