That looks like a good one....very similar to the one I got for my wife last year...it works damn good.
She "play's" farmville on it....unbelievable cpu usage on that silly game.... extra cooling was mandatory.
If'n ya have never disassembled a laptop....ya oughta...there's a damn good reason they are so "slow"...it's their inability to dissipate heat and battery life....not mention, imo....piss poor heatsinks and fans...just sayin'
