I just built a new PC and it has been fine for the past 3 days..but today the screen started showing black shapes and tears while playing WoW. Also the text on the desktop goes from clear to blurry..almost flickering. I uninstalled and reinstalled the GPU drivers and programs. I also tried under and over clocking using the GPU tweak program it came with. Not sure what is causing the problem.
GPU temps range 40-60 Celsius, GPU clock 300-457 MHz, memory clock bounces 600-6400mhz(is this normal?), voltage is 1225-1387mV.
FX6300 six core processor
Corsair cx500 PSU
Asus directcu II oc hd 7790 2gb gpu
8 GB ram
I would stick with the HD 7790. It's a Hawaii-based card like the R9-290X and it has TrueAudio. It will be easier to just get a replacement and the performance of both cards is similar, nothing that you'd notice from one to the other. This is especially true if the GTX 650 costs more.
I highly believe the problem lies within the GPU Tweak program that the GPU comes with. I was messing around with it and whenever I press "default" the glitches start immediately. I restart my computer, play my game with 0 problems, collapse and start GPU Tweak..and hit default and the problems start.
I uninstalled this and have been playing for several hours without a single issue.
