So I am trying to upgrade my graphics card to the XFX HD-687X-CNFC Radeon HD 6870 Graphic Card - 900 MHz Core - 2 GB DDR5 SDRAM - PCI Express 2.1 x16. I started by uninstalling the old card/drivers put the new card in and for awhile it was not even sending a signal to the monitor (I assume because I was getting no display). After reseating it the display came up. I installed the new drivers (or windows did) and it worked fine for awhile....that is till I put any kind of a work load on the GPU (ran a game or put the resolution on max). Upon reboot I was getting all kinds of graghic anomalies. Everything from letters going across my screen during the mobo logo at boot then two large blue stripes going vertical during the windows load screen. Sometimes it will load all the way to desk top and other times I have to reboot.

So in short I am thinking either power supply or the card is over heating. What are your ideas?

That's a little misleading. The brand of the PSU matters, yes, but 650w is sufficient for a 6870, if its from a quality brand.

What's the make and model of the power supply?

And for the temp, in catalyst control, there's a section where it displays the temp of the card.

It could also just be a bad card. That does happen every now and then.
 
and this is part of the problem as I stated in my original post. With the new card I can not get windows to fully load.

Could be either one. I would try a different PSU first. See if you can get one from a friend and see if that helps. Or install the video card into a different computer.
