I recently bought a evga gtx 750 ti sc edition with 2gb of gddr5 vram (no six pin connector) and have been very disappointed with my purchase. I have updated my motherboard bios, my gpu drivers, completely uninstalled all remaining previous drivers, disabled on board video, and i dont know what to do next. here are my specs:

*APU: AMD A6-6400K 3.9GHz Dual-Core Processor
*Motherboard: Biostar A58MD Ver. 6.x Micro ATX FM2+ Motherboard
*Memory: Kingston HyperX Fury Black 8GB (2 x 4GB) DDR3-1600 Memory
*Storage: Western Digital Caviar Blue 320GB 3.5" 7200RPM Internal Hard Drive
*GPU: EVGA GeForce GTX 750 Ti SC 2GB Superclocked Video Card
*Case: Diablotek DIAMOND ATX Mid Tower Case w/400W Power Supply
*Case Fan: Cooler Master Blade Master 40.8 CFM 80mm Fan (x2)
*OS: Windows 10 Pro x64

i was previously running Radeon-HD 8470D (a integrated gpu within the cpu which utilizes 1gb of ddr3) and getting about 20 min. fps to 60 max. fps on borderlands 2 with low-medium settings. Now running the same graphical settings im getting 17 min. fps to 36 max. fps. This is very confusing and disappointing for such a gpu with high stature. Playing games such as battlefield 4 however on medium to high settings i get around 45 fps avg. with occasional drops.

i also have a 400w power supply with 25 amp on the 12v rail and this card only requires a 300w psu with 20 amps on the 12v rail. any help would be gladly appreciated! :)

The Athlon X4 860K would definitely be a big improvement over the dual core APU you have now. And there will be absolutely no bottleneck with it and the GTX 750 Ti. Be sure your board's BIOS version is up to date for the 860K. Although the website for that board doesn't specify that it needs any different BIOS version than the one that works for your present APU: http://www.biostar-usa.com/app/en-us/mb/introduction.php?S_ID=663#cpu
So it may not be necessary.

Anytime you OC a GPU or CPU, you always do so at your own risk. But it's fun to do. Just take it in small steps and keep an eye on temps.


Yes i have removed my display adapter (VGA) from the integrated gpu and am now using a hdmi port on my gpu to my monitor. I have also used the application and it hasn't helped. I need to know whether my apu is bottlenecking my gtx 750 ti sc or not. It has a decent clock speed but it is a dual core which some say is a problem. Is it likely that my apu is holding my new gpu back?
 
If it only happens in games that are well threaded, yes. Very good chance the APU is the weak link. But either way, the discrete card should still be faster than the iGPU. You might try running DDU ( http://www.majorgeeks.com/files/details/display_driver_uninstaller.html ) from safe mode and have it remove all traces of the AMD driver and the Nvidia driver. Then reboot and install the latest driver for your GTX 750 Ti and your OS. That would eliminate the possibility that there is a driver or some other software conflict happening.

If you ever have to use the iGPU again, you'll have to re-install the driver for it again, tho. If you don't have one on disk, you can get all the latest AMD gfx drivers here: http://support.amd.com/en-us/download
 


Thank you, but I have already uninstalled all drivers with a driver cleaner and reinstalled the latest drivers from nvidia's official website, which still has no performance boost. Im going to go ahead and presume that my apu is holding my card back substantially until i get a quad core cpu. I have also tried out other benchmarks and games and it seems to me that there are some games that require more threads based on your conclusion. If i were to have a evga psu with 500w 80+ would i be able to overlock my cpu or gpu or both? I here that overclocking with nvidia's precision X 16 helps with performance substantially but may reduce its life in the long run. If I were to upgrade from this apu to a AMD Athlon X4 860k 3.7ghz quad-core processor, would i be able to see a performance boost in games and processes overall? Your input?
