what cpu to buy?????

[hellraiser06]

hi all
i got an intel d101ggc mobo with 1 gb of RAM, a p4 2.8 ghz processor, msi 7300 gt ddr2 and a monitor capable of displaying upto a resolution of 1024*768 😳
while playing games such as doom 3 or quake 4 my fps sometimes reach 60 on high settings but when i am midst of a heavy gun fight it drops all the way down to 9 10 fps...what do you think is being the bottleneck:the cpu or the absence of a sound card?i play in 2.1 speaker setup or headphones.
if its the cpu what cpu should i go for????
and a few days ago i noticed a weird thing:while playing call of duty 1 i was getting 60 fps consistently but on one level where we have to desroy incoming planes the sound went bitterly choppy and the fps reached 18....whats causing this problem????
please help...

I'm thinking the video card is the bottleneck there. Do you have the latest drivers installed from Nvidia?

yes i have the latest drivers 91.47...
but how can a 7300 gt be a problem for a game as old as call of duty 1????
and i finished prey wid high settings at 1024*768 with average fps of 30 35..in dat game the fps never dipped to 10 or even 15..i think the minimum was 20...but in quake 4 it went to 10 very easily eventhough the latter has graphics inferior than prey.....
thanx for the help.....
