[citation][nom]scatman[/nom]Why oh why there is never a good low end integrated or at least reasonably priced GPU given for comaprison in the charts. The numbers are quite helpless until I understand how much money I must spend to get N time the performance. People buy card only very rarely - and mostly are coming from low end or at least 2-3 generations back - never from another super card. So at least one low end comparison would be nice to show what this amount of money can do.[/citation]Reviews typically compare a special card like this to it's alternatives--that's why all the cards here are comparable.
On a major card launch, like the GTX 560Ti, you'll see it benchmarked against a larger variety and you can compare that, as the 100% baseline for these tests, to how the GTX 560Ti did against a GTX 460 1GB at launch.
Then compare how a GTX 460 1GB did (use Google) to a GTS 250 to get an idea of how this card compares to an older card like an 8800GT. If you want something specific--you have to do the work yourself!
So VERY roughly, GTX 560Ti 448 = 112% of GTX 560Ti. GTX 560Ti = 140% of GTX 460 1GB. GTX 460 1GB = 200% of GTS 250. GTS 250 = 130% 8800GT. That means a GTX 560Ti = 1.12*1.4*2*1.3 8800GT = 400% of 8800GT, or 4x the fps--which sounds about right. Of course, an 8800GT only has 512MB of DDR3 VRAM, so there are other drawbacks where you'll have to reduce texture settings with old cards. I don't know what old card you're thinking of, but an 8800GT is a good comparison card.
You can't compare low end integrated to a high end graphics card--it's like comparing a bicycle to a special edition Corvette. They both can get you from A to B--but they barely are serving the same purpose.
