Did My Video Card Upgrade Just SLOW Things Down?

I'm running a system that is pretty topped out. It has a FM1 motherboard (I believe that's the proper name) which only allows me to have a quad-core CPU with 8 Bs of RAM installed (which is exactly what I have).

Since I was looking for a speed bump, I took the only option available. I upgraded from a GeForce 9500GT to a GeForce GTX 750 TI video card.

Call me crazy, but I swear my video rendering has SLOWED DOWN! Sure there are a couple of games on Steam I can now play at full resolution since the upgrade that I couldn't' before, but several of the videos I export in HD from Adobe Premiere seem to take about 2-3 times LONGER than before!

I'm shocked by this, as I expected the exact opposite result. Could it be this card is to powerful and my system is having a hard time keeping up? Should I downgrade back to my old card to retain speed?

Thnx

 

First, thanks for the speedy response. I gave thanks above.

Second, the drivers don't seem to be the issue. I always run the most up-to-date drives on all hardware. My video drivers were updated as of the most current drivers when I installed the card last week, and my chipset drivers are already current.

Also, my issues are pertaining mostly to rendering out of video. For example: it used to take my about 17 minutes to render out an HD video at 720p that is about 30 seconds in length. Now it can take anywhere to 30-45 minutes (depending on the effects I'm running).

How could this time have increased if my video card is now more powerful?

 

If I'm understanding you correctly, you're referring to doing a complete clean intall of the old video drivers correct? If so, I am quite versed in this as I've done it many times in the past. This last upgrade, I took extra precausions. I not only manual uninstalled all the NVIDIA software through the normal ways, I looked up articles on how to remove all the hidden files/folders and entries in the registry (via regedit) by hand. I also CCleaner to get rid of any left over cobwebs. Then, just for good measure, I ALWAYS select "Perform Clean Install" when installing the latest driver just as a last precaution.

To answer your question, the exact model of my video card is the EVGA 2GB GDDR5 GeForce GTX 750Ti with GPU Boost 2.0. Also, I looked at your link and my version of Adobe Premiere is CS4 so I'm not sure it applies.

Any further thoughts on why I'm suddenly being bogged down even with upgraded hardware?

 

coincidence?
Check what else you have running, maybe something "upgraded" while you were installing, like an antivirus or Flash and that is causing problems.
Could the new driver be running at a higher resolution?
I would download Furmark and test with the old and new card, be sure you run the exact same test for each card. This means a couple of clean driver installs but should give very clear results.
