You can't just put any part you want into your computer. It needs to actually support
it. Do not attempt any upgrades to your computer until you learn at least the absolute basics.
As far as DDR2 vs DDR3, the latter is much faster, but your memory isn't likely to be slow enough to cause any slowdown anyway. As far as gaming goes, your memory speed is one of the least important factors in overall performance.
