Well recently ive been getting into gaming again. And currently im playing TF2 and Garrys mod...but when theres alot happening in the screen my fps goes down.... My current video card is a ATI RADEON x800 pro 256mb...and my ram right now is 2g...should i ad a gig of ram or get a bttr graphics card|||It's your graphics card...it's being overworked. Try the radeon x1950.|||2GB of system RAM is plenty. There are two things that you want to be fast for a gaming computer: the video card, and the processor, in that order. Just don't be surprised if you still get fairly low fps when there's alot of action on screen, with the faster video card-- it'll happen because your processor can't keep up.
