AM2 or AM2+

I'm about to upgrade (Athlon 2800+ just doesn't cut it anymore, not to mention my inability to get a new Graphics Card).

I'm wondering if I should go for a Motherboard with AM2 and DDR2 RAM, or AM2+ and DDR3 RAM.

If I go the cheap way, I can afford it come october hopefully, if I go the whole way, I won't have enough money until January.

I'm planning on not upgrading for a while, the computer I'm using now is like five or six years old.

Wait until AMD releases their Quad-core processor.  It's gonna raep Intel's half-assed Core2Duo up the ass
