I did learn from my error tho, back when I built my first W/C rig I went with two 8800GTS in SLi and it cost me £700 in GFX alone, never mind the EVGA mobo (£190), Q6600 (£150), 4GB RAM (£100), watercooling gear (£350), various HDDs totaling 4TB storage (£???),850W PSU (£90) and a Lian Li V2000 (£200) to stick it all in
Clearly that was a time before I had the Zed
