Im using this pc as download rig but lately some kids even my mom start using it but its rather laggy especially playing flash games or youtube The spec is single core am2 sempron 1600+, 2gb ram and onboard vga Im thinking a cheap vga or hunt for a old amd x2 proc, which should at least make youtube and flash game smoother and not laggy..add a vga or change proc?
If you want to accelerate flash content only, upgrading graphics card should improve performance. But if you don't game, I think a processor upgrade is better.
Yeah, if you want to improve flash performance, upgrading the graphics card would help more than a CPU upgrade.
Ram is usually the best upgrade for an old computer, or a minor graphics upgrade if you're running on an old integrated solution. for the price of an SSD > 60gbs you have half the price of a new machine and should probably start looking at going that route.
