Would I see any benefit from...

Upgrading a X2 5200+ to an Athlon II X2? Say the 240 or 255. Or a jump from the Athlon to a Phenom II 550?

What kind of performance loss would I see buying an Athlon II quad over the Phenom II quad with the L3 cache?

10-15% depending on app

What about a Phenom II X2 over a Athlon II X3/X4? I'm trying to minimize costs on the processor upgrade for the time being.

If you game.
Go Phenom II.
If you don't game often.
Go Athlon II.
Doesn't matter core numbers.

For gaming Phenom II X2 > Athlon II X4
