What should i upgrade for recording ? HELP

[bytard]

Hi i have custom build my optiplex gx 620 mid tower with specs :

Pentium D 940 3.20 gHz

ATI Radeon HD 5570 low profile

Intel 945G Moderboard

2 Gigs of Ram

WD black scorpion 300 gb

What more do you need to know from above?

Now to the question. What do i need to upgrade or just buy so i can record games much smoother? Right now it is from 25-60fps some games 70. I play Mw2 Dead island terraria Portal 2 etc. Can anyone please help me?

You need another 2GB RAM.Maybe a better video card. 6750-6770.First upgrade the RAM. With 2GB you are verry limited.
