I have been building, moding and upgrading systems for years but would like some extra insight on the APU's.I have an Acer Aspire 5560 with a A6-3400M Radeon HD 6520G graphics.I read much about the APU's but would like to know if it would be upgradable.Now from what i understand is that APU's have integrated graphics which i would like to upgrade to either an A8 or A10(7000 series graphics).I dont know if the A8 and A10 would be compatible because the socket of the A6-3400M is socket FS1 but the A8 and A10 are Socket FS1 (FS1r2) which i would like to install.There are a few versions of the A8 that might be compatible but the graphics arent as good as the newer 1s.There are many versions of the Acer Aspire 5000 series which have different APU's so im guessing its possibly upgradeable.I contacted acer but they say they dont know because they havent tested the 5560 with other APUs.Any exstra info would be helpfull.Thank You.
