Is upgrading from a GT 610 1gb to a GT 640 1gb worth it?

Before you say no and get money for a better GPU, I'm only looking to play games such as minecraft or garrys mod. I'm also able to over clock it with MSI afterburner. I just want to know if there will be a difference between both cards. I know that the GT 610 is 64 bit and GT 640 is 128 bit. It is also better in general, I just want to know if its worth it.

Just look at bottom about reasons to consider the 640.

Trust me 640 is so much more worth it, way it works with vidia cards is simple 610 = 10 very low end

40= low/mid range…60 is mid range and 70 80 90 High end.

The 610 is so **** it should not be called a graphics card…640 is at least a real card that lol… Mine craft will work a treat.

It is worth it, it is about 2x better than the 610

Even though the GT 640 is a definite upgrade to your previous GT 610, both cards are outdated and significantly less powerful than many of the popular ones on the market. I would recommend getting at least a 7750 because it's pretty cheap for its performance level or save up for a significantly stronger graphics card because the GT 640 will become obsolete soon as games become more and more GPU-intensive.

The 640 is a big jump from a 610 however its still not up there for high end gaming. You might want to look at a 650Ti but then you will need a more powerful PSU

Nope. Go with a nvidia gt545. Or a AMD HD5670.
