Yeah, currently have a 5770 and was never too happy with the performance.
was thinking of upgrading for BF3 and ME3 to something like a amd 6870 or a nvidia 560, around that pricerange.

oppinions/options?

current specs:
AMD phenom II x4 945
ATI 5770 cucore
4gb ddr3
some random Asus HN7something motherboard.
coolermaster 640W (would probably need to up that aswell, power jump to these cards is quite a bit.)
