Hello, I'm new to liquid cooling.
I've had the setup (my first liquid cooled) for about 2 months:
CPU: Pentium D 935 (3.2)GHz
MB: Asus P5WD2E-Premium
GPU: Geforce 8800 Ultra
RAM: 2 GB PC6400
PSU: 650W
Case: Koolance PC3-725SL
Cooling Setup: 1/2" Tubing running from Reservoir>CPU>GPU>Pump/Radiator w/ Fluid XP+ Coolant
Nothing is overclocked
Anyway, I've been having problems with Crysis crashing after a few minutes of playing. The point at which it would crash ranged from 5 to 20 minutes or so. I initially tried updating/changing up drivers with the assumption that was the problem, but then I downloaded a temp monitoring tool and played Crysis for about 15 minutes, closed it and checked to see what my temps were. It reported that my CPU was running at 52 deg C at between 75-90% load which isn't bad as far as I know, but the video card was bouncing between 95 deg C and a whopping
105 degrees C ! 
Obviously this is why it is crashing, and even if it's not, it doesn't matter because these temps can't be normal and I need to figure out how to get more efficient cooling out of my system.
As stated above right now I have the liquid running to my CPU and then the Video Card. My question is, would I see huge difference if I swapped the order so that the liquid hits the Video Card first and then the CPU?
Thanks
