malaki86, I am using HP laptop AMD Turion 64 X2 Mobile Technology TL-58 1.90 GHz
RAM 2.0, 32 bit OS 140 Gig Hard Drive Windows Vista SP1 Home Premium. I don't think I'am running any intensive programs. I just thought the BU-353 would track faster. I think of purchasing this receiver
i.Trek M7 Bluetooth GPS Receiver (51 ch MTK, 15hrs, 1 - 5Hz User Configurable, Dual USB/Bluetooth)
