Ok, plugging my PC into the wall outlet has gotten rid of the shutdown problems. At least appears to be, played games and benchmarks for hours now with no shutdowns. So I'm fairly confident this problem is solved.
However performance has not changed at all.
Could I possibly have damaged the card by not plugging it in right? (using Y adapter and not directly to PS) Or from the power drain on the UPS with the shutdowns?
Jackson, yeah I understand what a bottleneck is. It's basically hitting a limit on possible performance due to a single piece of hardware. But man, when I bought this rig just 2 yrs ago my CPU was above average, not high end but still up the ladder a good ways. Has CPU tech really taken off since then or something?
CPU specs: Mafia 2 is 2.4 GHz Quad Core processor
Arma 2: Quad Core CPU or fast Dual Core CPU (Intel Core 2.8 GHz or AMD Athlon 64 X2 4400+ or faster)
Would I be better off sending the card back and instead hunt for a CPU upgrade? Then eventually down the road shop for a new card? I'm feeling like I bought the wrong upgrade for my system.
Or I could try OCing my CPU and see what kind of results I get to see if it is worth keeping the card or not. On that note, is there any CPU OCing guides for a complete noob?
Also here is my 3DMARK11 benchmark.
Btw, with so much GPU memory now, only 3GB is seen of my 4GB installed memory. It use to be 3.3GB with my old card. So that certainly doesn't help performance either.
Once again, thanks for all the feedback, it's much appreciated.
