Hi guys, I am currently looking to upgrade my computer for use as a mid level gaming computer. I am looking to play various Source engine games such as Counterstrike, HL2, Garry's mod, and the like. A friend of mine recommended that I look into getting a new graphics card, He suggested that I look into the GeForce 8400 GS and the Geforce 210. I have very limited knowledge on the subject of computer upgrades and am wondering if these are good choices and if they are compatible with my system? I am also wondering if installing one of these would allow my computer to properly run Garry's mod and other source games?
Those are pretty old cards and you won't get good results with those.
You better get a Hd 5450 or a hd 6570. If you can afford cards about $100 then go for a GTS 460.
If you don't get it get a HD 7750 $100
