I hadn't planned to make any more tech purchases once I'd gotten my CoolerMaster Cosmos II and a Z97 motherboard to upgrade my i7 4790K rig, but plans do not always go to plan, as I found out yesterday, now. So there I was, trawling through price comparison pages for PC tech, as you do, when I spied this ASUS ROG Mars 760 Dual GPU graphcs card going for an unusually low price... and better still, the place selling it is just 20 minutes away by bus. Anyway, to cut a long story short...
