It will but gtx 1050 will very well bottleneck q6600. In my opinion, buy a used gtx 750 ti. It will be a good match for your cpu. But if you want to buy something brand new, I would suggest a gt 1030 which is almost as powerful as gtx 750 ti. Of course you could also sell the whole system as it is probably a ddr2 system but no worries, it will run games like csgo and other up to 2014 on very nice settings.
