This particular Thinkpad Edge (E545) has the AMD 2C A6-5350M processor (2 cores, 2.9 GHz, 1MB cache) which accelerates to 3.5 GHz...not bad for a laptop...but I can only game with low settings/resolution! So I would like to know if I could upgrade the processor? Lenovo's support says this models' CPU/GPU can be upgraded,but it doesn't show what is compatible. I'd appreciate your time and assistance in regards to this matter and I thank you in advance! Ron
