hi the 5770 and 5830 are the same price on ebuyer, yet it seems that most reviews say that the 5830 is about 30% better, some reviews also say that crossfire scaling is quite bad, but i read up on it and found that the scaling has been fixed with recent drivers.

i also read that the 5830 can be overclocked to perform at the same level as the 5850.

i am aware of the higher power usage of the 5830, and of the size of the card, but should i buy it?

5830: (£83.99)
