I am very hesitant about buying HP Pavilion dv6-6b00ee (with AMD Radeon HD 6755G2 1 GB DDR5 dedicated, up to 3.98 GB total) or HP Pavilion dv6-6C01ee ( with HD 6520G + 7670M Dual GPU 1 GB DDR3 dedicated) which one is better ?? the price is almost similar the 6C01 has a little bit higher price and the only more difference is the Clock speed of the processor the 6B00 is 1.6 GHZ while 6C01 is 1.7GHZ... Thanks in advance.
