I have a AMD Athlon 64 X2 Dual Core 3800+ 2Ghz processor. I have upgraded memory to the max capacity of 4 GB and upgraded the video card to a Sapphire Radeon HD 7750 1GB plus upgraded the Hard Drive to a WD Blue 1 TB. What I want to know is what would be the best processor upgrade for this computer? I have looked at a AMD A10-5800K APU 3.8Ghz Processor. Would that work or not? Suggestions?
