Are you kidding? I gave my old 9800GT to a friend, and he was blown away with how powerful it was... I mean, come on, this was basically the first card that would max out crysis with playable framerates. For a non-hardcore gamer it's an amazing choice; it'll max WoW, LoL, almost any older game... And it's about $40, used.
The 8800GT (which was later rebranded as 9800GT in the next gen) was a pretty good card. At the time it smoked pretty much everything.
Had one in the rig before my current one, you could get playable frames of pretty much everything if you were willing to lower some settings.
