Hello. I have a geforce 7900gs and I want to upgrade it with a new GPU. I don't have much money ( a bit more than 100 euros)
I already searched and found out that the 5770 would be the best, but I'm not sure if I can afford it.
My choices are these 4:

Is there a big difference bettween 512mb and 1gb? Is it better a 5750 with 1gb or a 5770 with 512mb?
Plus I found the 5830. I'm not really willing to buy it since it's more expensive and it consumes more power. But I'm asking just in case I can find one used for cheap. How well does the 5830 perform in crossfire in comparison with the 5770 in crossfire? What GPU can I use to crossfire it with? Only another 5830 or also another from the 58xx series?
If you have any other GPU (nvidia cards as well) to advise with similiar performance and price, advise it =)
I can already tell you that I'd rather buy a 57xx than a 48xx because of eyefinity and power consumption.
