yeah getting 2gb ram is wise choice at this time
and first try to get liteon dvd writer because IMO its better then all others but its difficult to find liteon dvd-rw
and if you have more budget then i once again recommend you gts450 because in performance its much better otherwise a 4850 is better choice over the 9800gt 4850 beats 9800gt in each and every benchmark
also check this for more info
