Lazy Unicorn
i bought dod source and i have half life 2 and cs; source and stuff, but my comp although fast wont run them very well. i get alot of lag and have to turn the graphics way down. i attribute this to my "shared video memory" I have an HP computer and need some ram. What do you guys have lying around?? What would you recommend i get thats around 100 or less and that would work for those games no prob...the specs on my machine as of now are as follows

2.8 Pentium D Dual Core Processors
1gig of ram
256 or something shared memory for the loos3

what could i get that would run them?
