Will my budget motherboard bottleneck an Nvidia GTX 570?

this is my board:

BIOSTAR H61MGC LGA 1155 Intel H61 Micro ATX Intel Motherboard

http://www.newegg.com/Product/Product.aspx?Item=N82E168...

my cpu is an intel 2500 quad-core 3.3ghz

was thinking of upgrading to a gtx 560 or 570, but don't want to have to replace any other components in order to get the most out of the card (i currently have a radeon 6850 and its fine).. i have a 600w corsair psu and that seems to be more than enough to power my whole system

basically i want to be able to run witcher 2 at ultra settings
