making text and fonts sharper

[rajesheber]

I have a sucessfull snow leopard installation .
Spec:
Proc: Quad core q6600.
MB: Gigabyte GA-G31M-ES2L
Graphics: XFX Geforce 8800Gt 256-MB
Monitor: Viewsonic(1680x1050)


After installation i find that the text is not sharp on all the apps or any PDF that i try to read. Is there a way to make the text sharper.Now the text looks more or less distorted.
