They're different architecture, but I was equating performance. Also, a 480M is nowhere near a 465. While its the same GPU, a 480M runs at a pitiful 400Mhz... enough to knock it down the GTS 450 performance levels.
Right, but that is just to save power/lower heat and those are nVidia stock clocks. You can definitely get overclock it to higher speeds. The nowhere near is a bit harsh. The 480m has 352 Cuda cores versus the GTS 450's meager 192 and that does matter. But, honestly you can't be sure unless you benchmark them.
This topic has me rethinking the power of my 9600GT M. Man I fell so far behind. A year and a half gone and there's mGPUs three times the power of mine for the same price.
How about your CPU? For the same price a probably when you bought it, it has more cores, hyperthreading and TurboBoost.
