Of all of them the MSI Lighting would be the fastest but since you don't want it because of the VRAM I would say get the MSI twin Frozr.
Dunno Which ASUS card you are talking about but if it is the Direct CUII then that one will be coolest.
So its like
Cooling - ASUS<MSI twin frozr=Msi lighting
Performance - MSI lighting<ASUS=Twin Frozer
So get the ASUS card if it is the Direct CU version
You're bit hampered by storage. My guess is budget restraints kept an SSD outta the build but if ya can't squeeze one of those in, a hybrid SSD / HD can give ya some of the best of both worlds. Without a benchmarking program, you would be hard pressed to discern the difference between an SSD and HD combo versus a hybrid SSD / HD. And only $30 more than the WD Black for 50% more capacity
