I'm a college student right now, most of what I learn is from text books and the internet. Am I wrong in thinking school is ultimately for a piece of paper that proves you paid thousands of dollars to a university? Sure some schools offer real world experience like internships, but what about the schools that don't? I'm a 4.0 right now and barely even pay attention to lectures...
You need someone qualified to evaluate your work. That's the main purpose of college/university.
@shinboy630: I'm using the EVGA Precision tool aswell as CPUID HWmonitor - both show the same temperatures. I noticed a slight drop in temp when forcing the speed to 100%. I just then tried moving the cards - one on a 16x slot and the other on a 8x slot which is way down the bottom. There was a 14c+ drop in temps when I did this but i'm not sure if this will affect performance if its now in an 8x slot.
Just run some benchmarks. I've looked at many 8x vs. 16x benchmarks and the differences are minor.
The other problem, i'm running a Noctua NH-D14 cpu cooler, so the new case must be able to house that comfortably.
I googled the case you have and it doesn't seem particularly bad. If you think it's the case or case fans that aren't allowing for good air flow, try opening the side panel and check the temps. Also, do you have the stock gpu heatsink/fan that blow air out the back or EVGA's own coolers that blow air back into the case? IMO, usually, the stock coolers are better for SLI/crossfire setup.
BTW, I have two graphics cards and no heat problems but my motherboard has a better layout, allowing for a gap. As you said, the lack of a gap is probably the biggest problem.
