I felt gtx 550 ti is a better choice, but the gt 640 has double the amount of cuda cores. I am an average gamer. i3-540, dh55pj, antec 450w, 6gigs, 250gb hdd, monitor with res 1366 x 768. Which card would be better for me. The gt 640 is cheaper.

Stay with the GTX550Ti, the GT640 is far to starved for memory bandwidth and so there is much more lag than with other cards. The GDDR5 version is close to the same performance as a 550Ti but they are hard to find. Just wait two weeks and there should be a GTS650 on the market.

I doubt the 650 is going to be all that impressive either. Judging by the specs it's an overclocked 640 with DDR5 RAM instead of DDR3.

If you already have the 550Ti, stick with that for now, and save up money to upgrade to at least the GTX 660. If you don't have either card now, I say wait a week for the 650 and 660 to launch and see how they perform and how they are priced.

If you absolutely have to buy right now, I wouldn't recommend either card, and say you should get the Radeon HD 7770, it's priced similarly to the 550Ti while being a good deal faster than the 550Ti. It only really makes sense to get a 550Ti if you desperately need an nvidia exclusive feature like PhysX (the 550Ti and 640 really aren't powerful enough to use PhysX effectively), or CUDA acceleration.

Keep the GTX 550 Ti and save up for something better. Where I live, the GTX 660 Ti is the best "bang for the buck" at $300, and the best "bang for the buck" at $200 is the HD 6850 or 6870 (if it's on sale.)

If you have the 550Ti already, just keep it. If you don't have it yet, get the 7770 instead.
