Hello,I have a old pc that i build like in 2003, i updated the agp 512mb card hd and it has hdmi, but play in the game its still lag and the graphics was great! My system is a intel(R) Pentium(R) 4 CPU, 2.60GHz, 2.60GHz,2.00GB of RAM. Is my pc too old to updated? and I also found out my enthernet lan is 10/100 and i look at other new motherboard was like 10/100/1000, does that make any difference on the online gaming? if it does should i replace the ethernet lan with the 10/100/1000 for the desktop? Sorry for the crazy question just like to know should i even waste money on the old pc or just buy a brand new mother boards and start fresh.
