Here is the specs of my Rig.
My question is, what is this card comparable to in terms of invidia? I feel like this card is holding down my rig in terms of gaming. I can play dota2 and league of legends on ultra high settings perfectly but when i try to play mmorpg games like runescape and W0W i can lag spikes frequently. All drivers and bios are updated and temperatures are all below 50 degrees. If this is the cause, im thinking about upgrading to a gtx 960-980. Thanks!
