Gaming Graphics

What type of computer do you have?and what type of computer specs is it?(mobo,prossesor,ram,etc.)
I'm thinking it looks like you will need a new graphics card.
How much money do you have to spend on that?

This is my system info:

I have the following system. It should be more then enough to play counter strike: source as smooth as it can get. BUT I LAG. i can't join a map with more then 10 people because i get this 5 seconds lag spikes. fps stay below 30 all the time, usually they stay below 15 fps. i have tried reducing the amount of ram memory in use but nothing.

I also have an ATI Radeon 3100 graphics card. version: 8.634.1.0 with 1918 MB. only 256MB are dedicated the rest is shared. i tried to increase the dedicated amount by entering the BIOS and doing it manually, but i couldn't find the option to do it. I called Toshiba to ask them and they told me the system is suppose to do it automatically, but it doesn't. It stays the same when i open Counter Strike: source. I bought this laptop foolishly thinking it would give me a smooth CS:S gaming experience and after a year, it has not. I don't understand, i go beyond the system requirements. WTF!!!!

PS: i have a DirectX version 11. CS:S only requires DirectX Version 7

I'm not very familar with laptops but it looks like you have a 256mb card, the shared system memory doens't mean anything i have no idea why.So you have a 256mb card trying to run Windows 7 and CS:S and i don't think it will work very well, have you tryed lowering your graphics settings?
A little experiment:go to Office map and go into the Projector Room and see if your FPS increase's and is playable in that room.

I have a 1G card and i don't even have an Onbaord graphics card and it says that i have a total shared system memory of 2814mb so really only thing to look at is how much you have thats dedicated.

You CANNOT increase video card dedicated memory (The memory ON the Card).

At least to my knowledge  

Video Card card memory doesn't equate to performance. It does when you run crazy rez and AA, but you need a card that has the horsepower to drive that. Dedicated is what is on the card, shared is taking from the system RAM (The normal computer RAM).
