7800GT is a great card, however, everytime someone asks for a card here, it's not in the high-end price range, so you don't see anybody recommending it.
There's nothing wrong with it, just a bit pricey for a large majority of us here

I'm not nVidia or ATi biased, but I have to say this - even X850XT PE isn't on par with 7800GT, no hard feelings.
In 1024x768 it is on par (about 2-3% behind) with 7800GT, however, up the resolution to 1280x1024 which is a standard today, throw in AF and possibly some AA and it's left in the dust behind the 7800GT.
Don't get me wrong, it's a great card, and I have only good things to say about x8x0 series, however, I couldn't say they are on par with GF7 series...
Just showing that it can compete with such a powerful GPU earns my respect.
