    ■ Video Card - PNY 770 GTX 2gb plugged into PCIE1 (monitor is plugged into the GTX via HDMI)

2) Full description of the issue:

I'm trying to game at 1920x1200, trying to play both BF4 and Far Cry 3. NVidia Experience indicates I should be able to play these on High/Utlra. This proved very quickly to be false, and I dropped the graphical settings very quickly to low (AA off) on both games, which has made little difference.

I'm able to sometimes run decent framerates (60-100) as soon as I start a new session of BF4, but they are very short lived, and I'm in short order running in the teens or worse. FC3 is no better -- I cannot even have an engine rendered cutscene play smoothly. I don't know the setting to doublecheck my fps in FC3, but to my eye it's maybe 30, then stutters under 15-20, and goes back and forth.

I see similar results in Uengine Heaven benchmarking (particularly with AA on), but with a better base frame rate (go/stutter/go/stutter):

Heaven Benchmark v3.0 Basic

FPS: 61.2
Scores: 1541
Min FPS: 9.0
Max FPS: 141.7


3) Attempted resolution steps

- Updated driver firmware
- went from win 8 to 8.1
- reduced graphical quality to low
- checked process monitor to make sure there weren't any competing resource hogs/startup items
- checked power management, disabled energy saving on the GPU and set CPU minimums to 100%
- installed EVGA precision and set a target FPS
- confirmed Ram is in DC config, the 770 is in PCIE1 and the monitor is plugged into the 770.

I'm at my wit's end here. Any help would be appreciated. I have a worthless $1,100 computer right now. I'd rather keep the hardware if there's an available solution than ship it back -- if you fix the issue I'll paypal you $20, dead serious.

tl;dr can't play games on low that I should be able to play on high/ultra
 
Solution
How do I go about checking to see if there's a PSU/RAM issue?

One way to check the PSU is with the Logging function of HW Info64: http://www.hwinfo.com/

The program defaults to log a plethora of otherwise unneeded information at a 2 sec interval, which is pretty long for monitoring voltages.

Go into the "Configure Sensors" menu and just pick out your voltages that you wish to monitor - especially +12 v. and +5 v. Set the monitoring interval to 250-500 ms. Start monitoring and start your game. Monitor it just long enough to see some of your problem artifacts because you will be saving a lot of data. Open the data in MS Excel, or the open office equivalent and check for wide voltage swings.

Good luck!

No overclocking done, no. I don't understand how either could be pegging at 1920x1200 on low with no AA?

This happens straight from cold boot. I can't imagine there's time for temps to get that high? I can boot, go to Heaven Benchmark and immediately see the stuttering right from the preview.
