I am looking into buying a laptop and I came across this one. I like it but I was wondering if I bought it, an Intel Core2Extreme Mobile X9100 3.06Ghz 6M 1066FSB 44W processor, and 8GB (2 x 4GB) PC2-6400 DDR2-800 200pin 800mhz RAM, would that be a feasable upgrade and will it function properly? total cost $1,370.
