I have a Emachines T5010 (its ok you can laugh) i just recently bought a ATI radeon X1300 (256mb) i had tryed to play css on my machine before and it was HORRIBLE i couldnt even move.. I had also tried to play hl2 and it lagged but i could deal with the lag being a hl2 nut. but anyways i bought the card to play css and hl2.the card ran Hl2 alot better but i still get a little lag and and in css it ran the game fine or so i thought untill everyone was complaining about how bad i was lagging... i only have 512 of ram. i was thinking about buying another 512 stick.. would it be worth it? do i even need it? im working with limited funds here.. lol or could the lag be caused by my internet connection? (you can tell i dont know much about computers) i have wireless internet. (clearwire) any help would be awesome thanks..
