Ok, so I have a pc with a 600w power supply, gtx 750ti, intel core I5 4690k, and 8 gigs of ram. I was planning on upgrading my GPU to a gtx 1050 ti. I was wondering two things, should I go with a gigabyte 1050 ti or a mail 1050ti? And for my second question, will my PSU be able to handle it? I was also planning on adding another 8 gigs of ram but I don't think that matters. Thx
