Ok me and my friend were playing left 4 dead and his computer would on run it on medium settings... and lag on high. This is because of his graphics card. He has 3gb of ram, an AMD Athlon 64 X2 5000+ 2.60 GHZ processor, but only a Geforce 8300 GS video card.
The computer that I am on has 3gb of ram and an intel core 2 duo with only 1.6ghz, but an 8800gts and it runs the game all the way up with ease....
So I know its the graphics card, and he wants to upgrade, but I do not know what his motherboard can support. Ive ran specs tests with "everest" but when I click motherboard, it says unknown, so I don't even know what motherboard is in here, to even begin looking it up.
