I have an acer aspire ax1420 model and was wondering if I can upgrade it I currently have the stock AMD Athlon II X2 220 processor with 2.8 GHz. also I have a low budget and plan on buying the Radeon R7 260X Video Card
There are different specs of that system but the same model. The one you have is a Athlon II X2, but another one is running on a Athlon II X4. If the other can run a X4, then your should be able to also upgrade to a X4 as well. For graphic card, it needs to be low profile, that means half the height of a regular card. http://www.newegg.com/Product/Product.aspx?Item=N82E16883103447
