GPU advice

[South890]

hello

I need some help as to what graphics card i should get. Was looking at the msi 7850 1gb but seeing as i have a AMD athlon ii X2 255 @ 3.1ghz this is likely to limit the performance at my resolution of 1440X900.

How much less performance do you think a GTX 550 ti or a radeon 7770 will give at this resolution?

i mostly play BF3

Thanks for any advice

thanks for the advice

Had another thought though. How would a A10 5800k perform @ 1440X900 on BF3 compared to my athlon ii X2 @3.1ghz with a 7850?

The A10-5800K will do BF3 on low to mid setting at that res, the 7850 will monster it though.

even with the bottle neck my cpu is likely to cause?
