Speaking from personal experience, yeah you may gain roughly 30% increased in performance, YMMV. I needed a dual dvi outs and the X800XL which I replaced didn't have that besides I got a great deal on the 7800 gt so went the upgrade. However not everyone likes GeForce cards so this is a good card for the $$$ for now.Originally posted by: amheck
I have one of these, too, and I've enjoyed it. But wouldn't the 7800GT be quite a bit better for $30 more?
