All:

I built a custom gaming rig about 2 years ago and am wondering how my framerates relate to other peoples. Relevant system components are as follows:

I5-2500K
16GB PC16000 RAM
EVGA GTX 560TI 1GB
128SSD just for games.

I have every graphical setting maxed and I am finding my framerates for the game fluxuate pretty dramatically. I'll be down to 30FPS in certain open world situations and then back up to 60 in others. For instanced areas, the FPS is locked at 60. I do not have this problem playing other MMOs at full-specs (GW2, SWTOR). I can max other games and play at 60FPS no issues (Borderlands 2, Skyrim).

Do other people have these types of fluctuations? Or has my 2 year old 560TI finally run its course?
